Python Core Developers Q&A - Ask a Core Dev Anything!
Welcome to the first Python Core Developers Q&A! During the Q&A, several core developers will answer questions sent in by you, the broader Python community. This Q&A is part of the yearly Python Core Dev Sprint, organized virtually this year on Python Discord.
The Q&A will touch upon a lot of topics, including the balance between features and performance, the direction of asyncio, how to start contributing to CPython, memory management, and many more.
Note: Questions for this Q&A were collected from September 24 to September 30. It is no longer possible to submit questions at this point.
