With its declarative approach, Pixi provides a reliable way for reproducible Python environments. Its design is based on experiences drawn from tools such as pip, conda and mamba as well as Rust's cargo.
Managing dependencies can be a complex task, especially when it comes to multi-platform support and extensions written in compiled languages, such as C/C++ or Rust, are involved. There are many tools for Python that can help to take care of different aspects of this problem. These tools are external Python packages that are not distributed with Python itself. Only pip is installed by default. Other, more recent languages such as Rust, include the tooling for dependency management as part of the core language. On the other hand, the Python ecosystem for dependency management is very fragmented.
In general, there are two main approaches:\n(a) based on pip packages and\n(b) based on conda packages.
\nPixi offers an approach that can work with both package types. Its design is inspired by Rust's cargo. In addition to Python packages, Pixi can also manage software written in other languages. For example, using conda-forge as the default conda repository, Pixi can install tools such as gcc, pandoc, or git. Pixi can work together with existing tools such as setuptools or poetry. In fact, it uses uv internally to install pip packages.
Please install pixi before the tutorial.

If a chess player moves a piece, we update the state of the board and persist it. This makes it easy to query the current state of the game, but also poses some challenges: How do we know which moves led up to the current state? And how do we ensure that the state remains consistent, even in a distributed system?
\nEvent Sourcing takes a different approach to storing state. Instead of storing the current state as-is, we store the sequence of events that led to the current state. If we need to know the current state, we can replay this immutable record of events to reconstruct it. Not only does this give us an immutable audit log, this also promotes loose coupling and enables optimistic concurrency.
\nIn this tutorial, we are going to build an \u201cEvent Sourcing\u201d-based backend for a game of Connect Four from the ground up. Rather than using a framework that abstracts away some of the core principles, we are going to implement the mechanisms ourselves to help us understand the core principles.
\nThis tutorial is for you if you\u2019re interested in Event Sourcing but don\u2019t have any real experience with it yet. We do expect you to have at least an intermediate level in Python, with some experience in writing (simple) classes.

And yet, magic methods make it easy to write code that implements often very complex algorithms in a readable way.
\nPython allows you to equip created classes with special methods, also known as magic methods or dunder methods. To recognize a special method, you should know that it is a method whose name begins and ends with a double underscore. But it's not the name that their magic lies in, because these methods have a special meaning for Python.
\nPython calls magic methods in response to fundamental operations, such as creating class instances, indexing sequences, comparing objects, managing attribute access, and more, so knowing how to create them is fundamental for any Pythonista.
\nDuring this tutorial, you\u2019ll:\n* Find out what Python magic methods are,\n* Understand the magic behind Python magic methods,\n* Learn how to create and use magic methods,\n* Customize various behaviors of classes using magic method.\n* Talk about some interesting non-trivial magic methods.
\nTo fully benefit from this tutorial, you should be familiar with object-oriented programming in Python.
\nThis tutorial will have classroom exercises, post class homeworks as well as complimentary readings. All the presentation, code, exercises will be shared in advance and the solutions of the exercise will be shared after the tutorial is completed.

As Python has become the language of choice for data science, pandas and scikit-learn have become staples in the machine learning (ML) toolkit for processing and modeling this data. However, when data size scales up, these tools become unwieldy (slow) or altogether untenable (running out of memory). Ibis provides a unified, Pythonic, dataframe interface to 20+ execution backends, including dataframe libraries, databases, and analytics engines. Local backends, such as Polars, DuckDB, and DataFusion, perform orders of magnitude faster than pandas while using less memory. Ibis further enables users to scale using distributed backends like Spark or cloud data warehouses like Snowflake and BigQuery without changing their code, giving them the power to choose the right engine for any scale.
\nIbisML extends the intrinsic benefits of using Ibis to the ML workflow. It lets users preprocess their data at scale on any Ibis-supported backend\u2014users create IbisML recipes defining sequences of last-mile preprocessing steps to get their data ready for modeling. A recipe and any scikit-learn estimator can be chained together into a pipeline, so IbisML seamlessly integrates with scikit-learn, XGBoost (using the scikit-learn estimator interface), and PyTorch (using skorch) models. At inference time, Ibis/IbisML once again takes the feature preprocessing to the efficient backend, and user-defined functions (UDFs) enable prediction while minimizing data transfer. This completes an end-to-end ML workflow that scales with data size.

\nThis tutorial will showcase how to harness Python tools to write automated tests, ranging from fundamental techniques to advanced approaches that make testing truly effective.\nThrough a hands-on live-coding session, we will follow a top-down approach: starting with principles, we will begin by testing simple functions. From there, we will move on to mocking external dependencies we can control and measuring the effectiveness of those tests. Finally, we will integrate everything tested so far, unveiling a complete testing strategy. The workshop will conclude with a recap and a brief handbook full of tips and more topics to explore.
\nThroughout the session, we will embrace the entire philosophy of testing: beyond merely spotting bugs, we will see how testing is a powerful tool for designing, understanding, and uncovering hidden issues in our implementation. We will introduce and practice test-driven development (TDD) while also exploring alternative approaches.
\nNeither extensive knowledge of Python (just some familiarity with classes and basic functions and ability to run Python scripts) nor special tools are required to attend the workshop: a little confidence with the basics is enough to participate, and a working Python environment is all we will need.

As demand in electricity grows and new forms of electricity usage emerges, so does the necessity to identify load growth patterns in real-time. As such, while Time Series Classification and Clustering is still an emerging field of study in the Machine Learning space, it has been one of the most relevant topics in the utilities industry. Efforts into applying Time Series Classification/Clustering in the utilities space, specifically pertaining to load, are ongoing, with a mix of both successes and failures. Aided by packages such as Aeon and Numpy, experimentation have included classification of existing load patterns through various models such as HIVECOTEv2, DTW+KNN, etc. at various granularities (yearly, monthly, etc.). Other experiments have included transforming load data into frequencies through discrete fourier transform and applying similar models. Some of the challenges faced have included classifying classes with low class priors (few cases in training data), identifying partial time series, and identifying new load patterns in conjunction with existing loads.

"}], "description": "Large Language Models (LLMs) excel at tasks like filtering, summarization, and code generation, but their high computational requirements lead to steep costs and limited scalability. This poster proposes a novel approach that breaks from the constraints of monolithic LLMs, moving toward a lightweight ecosystem of open-source Small Language Models (SLMs) coordinated by a central Master Agent.
\nIn this architecture, the Master Agent dynamically assigns requests to specialized Worker Agents, each running an SLMs (Phi3, Orca-mini, etc) tuned for a particular function. By distributing tasks among smaller, focused models, we reduce resource consumption and cost. Scaling up or adapting to new tasks becomes as simple as adding or swapping Worker Agents, avoiding the complexity and overhead of deploying an all-encompassing large model.
\nBeyond cost and scalability, this approach addresses the growing demand for edge-compatible solutions. Compact SLMs integrate seamlessly into edge devices ranging from IoT sensors to mobile apps which enables low-latency, privacy-preserving, and even offline language processing. This setup empowers developers to bring advanced language tasks directly to the user, regardless of infrastructure or connectivity constraints.
\nOur implementation, primarily in Python and supported by open-source frameworks like Langchain, Hugging Face LLMs, etc. to foster community-driven enhancements. The poster will showcase how this multi-agent framework optimizes resource utilization, simplifies maintenance through modular specialization, and ensures robust failover for uninterrupted performance. Attendees will learn how to integrate these components into their own projects, benefiting from a flexible, future-proof platform that\u2019s both affordable and adaptable.

"}], "description": "Early diagnosis is vital for significantly improving treatment outcomes for cancer patients, as the chances of successful treatment and survival greatly increase when the disease is caught before it spreads. A promising area of research in early cancer detection focuses on tiny, circular pieces of DNA called extrachromosomal circular DNAs (ecDNAs) or amplicons. These DNA circles are produced by tumor cells and can be identified in the blood or tissue samples of patients with various types of cancer. Recent advancements in DNA sequencing technology, capable of generating individual sequence reads as long as 100 kb, have made detecting these ecDNAs feasible. As sequencing costs continue to decrease, ecDNAs are now being sequenced from thousands of patients, creating vast datasets that require sophisticated computational tools for analysis.
\nTo address this need, we developed a bioinformatics tool named AmpliconFinder, which integrates a convolutional neural network (CNN) trained on long-read sequencing data from cancer patients with a robust bioinformatics pipeline\u2014all implemented in Python. The tool leverages powerful libraries such as scikit-learn and TensorFlow for CNN development, and pandas, numpy, and matplotlib for data processing and visualization. Circular DNA amplicons, which serve as early-stage cancer biomarkers, can be studied using AmpliconFinder, providing a pathway for doctors to harness cost-effective sequencing data for simple, non-invasive early cancer detection, ultimately leading to more effective treatments.

Executable examinations, where participants write, modify, or execute Python code to solve specific problems, are widely used in educational environments to foster learning and evaluate student progress. However, delivering accurate and constructive feedback on these assessments at scale remains difficult. This poster introduces ExecExam, a tool designed to streamline and automate the assessment of Python programming tasks through Pytest integration, enhancing student learning and the evaluation process .
\nExecExam leverages Pytest to automatically verify student solutions against pre-defined test cases but extends its functionality through advanced features such as tailored feedback reports, a user-friendly interface, and integration with large language models for enhanced programming advice. These additions make ExecExam more than just a Pytest test runner, offering educators and students a comprehensive assessment and learning tool. The system generates detailed reports summarizing test outcomes, highlighting successes as well as areas needing improvement.

Surprisingly, nearly 90% of packages published to PyPI using semantic versioning have a major release number of less than two. What makes reaching this milestone so elusive?
\nIf we applied software versioning to our lives, what version would we give ourselves? Perhaps in our formative years as students, we'd be a part of a 0.x series, and as we establish careers and become self-sufficient, we might progress to a 1.x scheme. But do we settle there?
\nJust like software libraries, our lives require maintenance, and despite our best intentions, hacks and workarounds inevitably infiltrate our routines. As these multiply and compound, our health can suffer. Do we wait for disaster to strike? Or, can we take a proactive approach in not only addressing problem areas but also striving for more?
\nTogether, we'll explore certain risks to our wellbeing inherent to our profession as software developers: sedentary lifestyles, long work hours, and social isolation, and how we can plan and design our next major release for success.
\n\"Finding 2.0\" is an invitation to reimagine what's possible across life areas. Whether facing health struggles, burnout, or feeling stuck in a rut, this talk provides practical insights and actionable steps for rewriting the code of your life and embracing a future of health and fulfillment.

This approach works well for single-node tasks, but scaling to handle larger datasets or more resource-intensive computations introduces significant challenges. Not to mention, using GPUs requires another level of complexity. We present the cuPyNumeric library. cuPyNumeric gives developers the same familiar NumPy interface, but seamlessly distributes work across CPUs and GPUs.
\nA compelling example when scaling is necessary is when scientists at the SLAC National Accelerator Laboratory need to process a large amount of data within a fixed time window, called beam time. The full dataset generated during experiments is too large to be processed on a single CPU. Additionally, the code often must be modified during the beam time to adapt to changing experimental needs. Being able to use NumPy syntax rather than lower level distributed computing libraries makes these changes quick and easy, allowing researchers to focus on conducting more experiments rather than debugging or optimizing code.
\ncuPyNumeric is designed to be a drop-in replacement to NumPy. Built on top of task-based distributed runtime from Stanford University, it automatically parallelizes NumPy APIs across all available resources, taking care of data distribution, communication, asynchronous and accelerated execution of compute kernels on both GPUs or multi-core CPUs. In addition, cuPyNumeric can be integrated with other popular Python libraries like SciPy, matplotlib, Jax. With cuPyNumeric, SLAC scientists successfully ran their data processing code distributed across multiple nodes and GPUs, processing the full dataset with a 6x speed-up compared to the original single-node implementation.
\nIn this talk we showcase the productivity and performance of cuPyNumeric library covering some detail on its implementation.

However, as datasets scale to terabytes, managing tables, evolving schemas, and ensuring consistency across tools becomes increasingly complex. Apache Iceberg\u2122, an open table format, addresses these challenges, and, with PyIceberg, seamlessly integrates with your favorite Python-based tools.
\nWe will start with an introduction to Iceberg and PyIceberg, focusing on the features PyIceberg brings to the Python ecosystem such as schema evolution and transactional guarantees. We will demonstrate how PyIceberg supports interoperability between Iceberg tables and Python-native dataframes like PyArrow and Pandas, using practical examples of creating, querying, and writing to Iceberg tables.
\nFrom these practical examples, we will dive deeper to explore how Iceberg tables evolve during these operations. This includes an in-depth look at Iceberg's file structure\u2014metadata files, manifest lists, and manifests\u2014and how PyIceberg leverages this structure to perform transactional table updates and optimize query planning, ensuring reliable performance at scale.
\nFinally, we will discuss PyIceberg\u2019s advanced features, including schema evolution, hidden partitioning, and time travel, which make table management efficient and flexible.

\nThis brings promise of significant performance opportunity, but not without cost. Parallel execution is notorious for being challenging due to the additional complexity. This implies bugs, and the risk is particularly high for the compiled code powering Python - including the CPython interpreter itself (it's written in C). The main risk comes from data races, which can cause unpredictable and potentially dangerous crashes.
\nThe Rust programming language is designed to prevent data races by construction; if your code runs, it should be data race free (unless you misuse unsafe Rust).
We'll explore the way that Rust does this, both from the rules of the language, and by the data structures it offers to complement those rules. We'll showcase this with examples of Rust (PyO3) code designed for \"regular\" Python 3.13 and how it changes to become compatible with the free-threaded build.
\nThis will lead onto ideas which we can carry across languages to influence how we write Python (and maybe C/C++) to be correct in a free-threaded world, before closing with some tantalizing examples of software architectures made possible by free-threaded Python.
\nNo prior Rust knowledge necessary.
\nWhat you should hope to take away from this talk:\n- a basic understanding of how the free-threaded build of Python is different to the regular one,\n- an appreciation for the complexity of free-threading for compiled code,\n- how Rust helps you reason about this complexity, and\n- excitement for the future of free-threaded Python!

\nPerhaps it's just because the APIs for controlling them are so different, and it seems difficult to get started.
\nIn this talk I will explain how to use Python to integrate with your desktop environment; how to schedule tasks, schedule notifications, and script the applications you already use.

This graph models how data flows across cells, and is used as an intermediate representation consumed by a runtime that eliminates hidden state while also powering interactive computing, scripts, and web apps.
\nBy using notebooks and marimo's internals as a case study, we'll examine a question that is broadly applicable to developer tools in many domains: What does it take to compile Python code to a flexible intermediate representation that preserves the original program's semantics? We'll discuss design decisions and tradeoffs along the way, such as the pros and cons of static analysis versus runtime tracing.

This is due to so many factors ranging from climate change to socio-economic factors. To combat this menace, there is need for a robust and scalable system like IoT for weather monitoring and informed decision making for both the policy makers and the farmers to be able to mitigate these challenges. Python, with its rich ecosystem, serves as a bridge between the IoT devices and machine learning, assisting in resolving these challenges and improving decision making in agriculture.\nThis talk explores the use of Python in delivering sustainable agriculture practices. We will look at how data is collected using Python from such IoT devices as soil, weather, and crop sensors. With the help of the Pandas and NumPy and SciPy libraries, we will also show how the collected information is cleaned up and analyzed for further decision making.\nThe session also emphasizes connecting machine learning solutions via TensorFlow, PyTorch, and scikit-learn toward enhancing agriculture. Such examples include estimating when and how much irrigation to apply, potential pest control measures needed, and when and how much pest control measures will be accomplished.\nAttendees will learn the mechanics of building complete pipelines beginning from IoT data collection to final deployment of machine learning models in cloud or edge devices. Other concerns which we will tackle include the quality of data, compatibility of devices, policies on expansion, and the solutions to these problems.\nThis talk is ideal for researchers, developers, and practitioners interested in leveraging Python to transform agriculture. By the end, attendees will understand how Python can drive innovation, sustainability, and resilience in this critical sector.

OOP is especially popular, in large part due to how it enables polymorphism (for example, calling speak() on a Dog object returns \"woof\", while a Cat object's method returns \"meow\".) However, OOP has many downsides that are often not understood until it's too late in the lifecycle of building a program. Fortunately, Python also enables developers to achieve similar behavior to polymorphism while using simple functions and plain data objects instead of classes.
This talk will detail three different approaches provided by Python to achieve polymorphism behavior in a realistic program. It will compare and contrast their relative strengths and weaknesses. It will show how the most naive approach, which relies on isinstance() checks, leads to severe code duplication. It will show how OOP method polymorphism leads to code being organized along the wrong axis, which hurts understandability, debugging, and maintainability in practice. It will also demonstrate a less commonly known part of the built-in functools library called @singledispatch that strikes a perfect balance between functional and OOP programming styles.
Finally, you'll learn how @singledispatch works under the covers, and how to build or integrate similar functionality into your own programs so you can realize the benefits of polymorphism while avoiding the pitfalls.

As PyPI comes under threat, how can we continue to secure our beloved cheese shop through 2025?
\nThe 600k packages in PyPI power sensitive infrastructure in almost every critical industry, and it's no surprise that the Python library ecosystem is a target. In 2024 alone, the Ultralytics token compromise and the NP6 combined typosquatting and DLL sideloading attack show the sophistication of these supply chain attacks.
\nIn the first part of this talk (12 minutes), we'll look back at these 2024 attacks and also consider examples such as the \"revival hijack\" attack vector and the 2022 dependency confusion attack on PyTorch. In the second portion (12 minutes), we'll dig into some critical developments in this area that have helped to mitigate recent attacks, such as:
\nWe will also briefly discuss specific insights from developing Chainguard\u2019s Guarded Ecosystems for Python, an ambitious alternative package index that rebuilds included packages from scratch. The final takeaway: while mitigations exist for these threats, they're not equally distributed, and we'll point out low hanging fruit for securing projects and infrastructure (3 minutes).
\nThis talk will be an accessible introduction to an intermediate topic (software supply chain security). Expect some cheesy puns and memes as we deal with this muenster problem\u2014all in excellent taste, of course.

In that case, typing may feel like just another task, not a tool that truly improves quality.
But like unittest, typing can reduce hidden issues and make you confident about changes, even though it does not add new features directly. If we maintain and improve our type hints over time, typing can become a reliable foundation for your project, making refactoring safer and Python upgrades smoother.
\nThis talk is not just another basic intro. We\u2019ll show practical steps with before-and-after code examples:\n- Use ideas from newer features (like typing.TypeIs in Python 3.13) and typing_extensions to apply similar concepts on older versions.
\n- Run pyupgrade (via ruff) to automatically update old hints, reducing manual edits and creating a consistent style.
\n- Apply partial ignores instead of full # type: ignore, and integrate pre-commit and CI checks to catch issues early, making typing checks feel natural.
\n- Add types to example code to detect subtle incompatibilities, similar to how tests find hidden bugs.
We\u2019ll also propose a gradual approach so your team won\u2019t be overwhelmed. After this talk, you should see typing as a stable base that reduces bugs, helps with refactoring, and supports long-term growth.
\nWho should attend this talk?

Yet sometimes we need both: for example, a tuple that starts with an int and a str and follows with zero or more floats might describe a row in a dataset that starts with identifiers and follows with a variable number of observations. While we might want to define a generic Record class that can be elastically parameterized in this manner, doing so was not practical until the introduction of TypeVarTuple and Unpack in Python 3.11.
With TypeVarTuple, a generic Record class can be made concrete as Record[int, str], Record[int, str, float], or even Record[int, str, *tuple[float, ...]]: the same class can be parameterized as requiring two types, three types, or required int and str types followed by zero or more float types (as given with the Unpack notation *tuple[float, ...]).
This presentation will introduce TypeVarTuple and Unpack. Starting with annotated tuple types, the flexible, expressive range of mixture between fixed and unbound types will be demonstrated with mypy validation. Next, a variadic generic class, Record, will demonstrate the benefits of such elastic typing.
Finally, a compelling application of TypeVarTuple will be demonstrated. While DataFrames are widely used, only the StaticFrame library, leveraging TypeVarTuple, offers a comprehensively generic DataFrame. DataFrames have variable numbers of columns, each sometimes a different type; further, while DataFrames might have tens or hundreds of columns, it is common for such datasets to have a fixed number of heterogeneously typed columns followed by a variable number of uniformly typed columns. With TypeVarTuple, this type of flexible DataFrame typing is now possible.
Christopher Ariza (www.flexatone.net) is Partner and Chief Technology Officer at Research Affiliates, a global leader in investment strategies and research. He is the creator and lead developer of StaticFrame, an alternative DataFrame library that offers immutable and statically-typeable DataFrames with runtime type and data validation.
\nHaving worked in Python for over 20 years, he has developed tools in a variety of domains, including algorithmic music composition and computer-aided musicology, and has spoken at numerous conferences, including PyCon USA, SciPy, PyData Global, PyData Los Angeles, and numerous other venues.
\nPrior to joining Research Affiliates, he was Visiting Assistant Professor of Music at MIT, Assistant Editor at the Computer Music Journal, and Assistant Professor of Recording Arts and Music Technology at Towson University. He has a PhD and MA in music theory and composition from New York University, and a BA in music from Harvard University.

Keynote
Have you ever needed to debug a Python application in production without stopping it? While tools like GDB make this straightforward for C/C++, Python developers face unique challenges when attaching debuggers to live processes. This talk introduces PEP 768, a new proposal for Python 3.14 that adds a safe, zero-overhead debugging interface to CPython.
\nWe'll explore how the current landscape forces debugging tools to use unsafe methods that can crash interpreters and corrupt memory. Then, we'll detail how PEP 768 solves these problems by introducing a cooperative debugging protocol that works with the interpreter rather than against it.
\nYou'll learn why attaching debuggers to Python processes is uniquely challenging, how PEP 768 enables safe debugging through interpreter cooperation, the technical details of the zero-overhead implementation, real-world applications, including live process attachment for pdb and all about the security considerations and safeguards.
\nThis talk will be particularly valuable for tool developers, system administrators, and anyone interested in Python internals or debugging techniques. You'll walk away understanding the challenges of live process debugging and how PEP 768 elegantly solves them.

These challenges have stymied past attempts to do large-scale end-user signing in the Python ecosystem, including PyPI's former (now disabled) support for PGP signature uploads.
\nOver the past year, PyPI has designed, developed, and deployed a new approach to package signing, one that aims to break the iron triangle of end-user signing: digital attestations, as standardized in PEP 740.
\nThis talk will cover the architectural details of attestations, how attestations were implemented on PyPI and on the client (uploading side), their security properties (including transparency) and advantages, as well as how PyPI was able to enable signing by default for a large swath of the ecosystem without requiring maintainers to change anything about their packaging processes. The talk will also cover the future of attestations, including pieces of the puzzle that are currently missing (like large-scale verification of attestations by parties other than PyPI itself).
\nThe audience is expected to have an intermediate familiarity with Python packaging, including PyPI. No specific familiarity with cryptography is required. Audience members will leave the talk with an improved understanding of the challenges latent in end-user signing, how PEP 740's design and PyPI's implementation overcome those challenges, and how they can both produce and consume attestations today.

Users can use locals() to get the same dict Python is using for the local variables. As Python evolves, local variables were moved to the frame stack to improve performance, which made it invisible from Python code. However, locals() was kept because we still need a way to access some or all of the local variables in a frame.
\nThis became chaotic when we try to change the local variables through the dict - which is a common requirement for something like a debugger. What could possibly go wrong? Is the update remembered? Could it work with exec()? Will a random read in your code bites you? How can we reliably update the value of a local variable in a debugger?
Well the short answer is - we can't, not until PEP 667.
\nThis talk will be about how we fixed the chaos in PEP 667 and what's the modern way to deal with local variables in a debugger.

This can result in the complete loss of both halves of the hive for the beekeeper. In this talk, I will show how I used a Raspberry Pi, mounted on a hive and powered by solar panels, to take a still image of a hive entrance every 30 seconds and filtered using OpenCV. Each image was sent off in real-time to Marvin.AI for analysis to obtain a count of the number of bees at the hive entrance. A subsequent refinement has removed the need for AI analysis using an object detection model implemented in PyTorch using large scale datasets from iNaturalist to create a deep learning model which I plan to implement this Spring. The counts were stored in an offsite database and then aggregated into a Pandas dataset and subjected to a rolling window analysis. It was postulated that such an analysis would prove necessary to distinguish between swarming and \u201cbearding\u201d which is when many bees exit the hive and congregate at the entrance during very warm periods to ventilate it. While the bees were \u201cuncooperative\u201d this season and did not swarm, test data show that a beekeeper could be notified of a swarm event within 10 minutes of its occurrence, thus saving both hives.\nAttendees will learn : \n(1) The use of \u201cmaker\u201d techniques in setting up and integrating solar power, Raspberry Pi systems and cameras as well as effectively running python on the systems and setting up remote access.\n(2) How to implement the setup and use of PyTorch data object models and how they relate to AI analysis\n(3) How to use NumPy and Pandas for biological system analysis\n(4) And maybe a little apiculture!

Python, known for its simplicity and powerful libraries, has been at the forefront of this AI revolution, offering robust tools for model building, training, and fine-tuning.
\nHowever, as AI systems become more embedded in society, one challenge that has gained increasing attention is \"Fairness in AI\". Fairness is a complex and widely discussed topic with no one-size-fits-all definition. For example, imagine a baker dividing a pie: should the larger slice go to the person who worked harder or the one who is hungrier? Similarly, in AI, fairness is defined by context, but it aims to ensure equitable treatment of all individuals or groups impacted by a model\u2019s predictions.
\nML models learn through data. Unfortunately, more often than not, data is full of historical inequities, imbalanced labels, or skewed representations\u2014that can lead to unfair outcomes. Addressing these biases requires tools that go beyond precision, accuracy and optimization.
\nIn this talk, we\u2019ll explore these challenges and go over a demonstration of how Python can help address them using the fairlearn library. Through real-world examples, we will learn methods to measure fairness using metrics like demographic parity, equalized odds, equal opportunity etc. We will also learn to mitigate these biases using GridSearch and ThresholdOptimizer.
\nPrerequisites: Whether you are a Python newbie or a seasoned Pythoniast, with any level of experience in Machine Learning, you are welcome to join and explore a piece of the pie!

In this talk, we'll talk about how digital audio works from the ground up (from sounds, to bytes, to files), how you can use Python to do a bunch of really neat things with audio, and how a Python library - Pedalboard - helps make working with audio much easier.
\nEver used a digital audio workstation (DAW) like GarageBand, Ableton Live, Logic, or Pro Tools? Today's musicians use DAWs as instruments in themselves. But what if you want to combine the power of a DAW with the flexibility of writing your own code?
\nPedalboard was built to fill this niche: to pull the power of a DAW into your Python code. Pedalboard makes it easy to build and apply audio effects, read and write audio files, and load audio plug-ins (\"VSTs\") without any complicated dependencies or frameworks. Just import pedalboard and go!

\nNext, we'll start to pull back the curtains a bit on how Python handles more complex control flow mechanisms, like generators and decorators, and look at ways to leverage those features to build higher order functionality. Lastly, we'll get a bit reckless and look at how Python makes it possible to create our own systems for control flow, and consider committing some light crimes in the name of code readability.
