The Memory Chronicles: A Tale of Two Pythons
MicroPython is the leanest, meanest full Python implementation. Designed for microcontrollers, this variant of Python runs in less than 300KB of memory, _and_ retains support for all your favorite Python features. So what does it take to make the smallest Python? Put differently, why does CPython have a large memory footprint? This talk will explore the internals of MicroPython and contrast it with CPython, focusing on the aspects that relate to memory use. We will delve into the Python object models in each and the machinery for managing them. We will touch upon how the designs of the bytecode compiler and interpreter of each differ and why that matters.
