🎤 *Become a Python Core Developer in 3 Easy Steps by Tomas Roun*
🔗 https://ep2026.europython.eu/session/become-a-python-core-developer-in-3-easy-steps
📝 Abstract:
Step 1: Fix a bug
Step 2: ???
Step 3: Core developer
Ok, it's not that simple but it's also not as mysterious as it might seem!
About three years ago I fixed an obscure bug in the unittest module. Today, I'm a core developer. This talk is about what happened in between, and how you can start contributing too!
Over the years, I got to work on many different areas of Python. I've fixed bugs in the parser, added import autocomplete to the REPL, worked on gettext tooling, and eventually found my way to the JIT compiler, all things I knew little about before diving in.
Getting started contributing to CPython can be intimidating, so I'll share some practical things I learned along the way. At the same time, I will spend some time talking about the whole process of how does one go from being "just" a Python user to becoming a Core developer (with stats included).
If you've ever wanted to contribute to Python but weren't sure where to start, this talk is for you!
