I've been using Python since 2012 and focus on bioinformatics. With Circuit Python I have enjoyed bring Python into my home, creating a 'somewhat smart' home, and more than that, I've enjoyed recording and analyzing data that I can actively change and impact so I can more rapidly understand a complex algorithm as it impacts values I have an intuitive sensor for.
Being active in online communities, and PyOhio, I enjoy seeing others build amazing things with Python, and as Python become more browser based, mobile deployed, and embedded, I'm really excited to see what people build.
