Python Language Summit


Python Language Summit 2020

The Python Language Summit is an event for the developers of Python implementations (CPython, PyPy, Jython, and so on) to share information, discuss our shared problems, and — hopefully — solve them.

These issues might be related to the language itself, the standard library, the development process, status of Python 3.9 (or plans for 3.10), the documentation, packaging, the website, et cetera. The Summit focuses on discussions and consensus-seeking, more than on merely presentations.
