Python has famous "batteries included" philosophy for its rich standard library modules, but there are lots of modules have been oudated or inactive for past years. With acceptance of [PEP 594], serveral modules will be marked as DeprecationWarning from Python 3.11 and be removed from Python 3.13, and Python on mobile platforms like BeeWare or WebAssembly (e.g. pyodide) also will benefit from reduced download size.

Part of proposed modules: cgi, crypt, smtpd, telnetlib, ...

PEP 594 – Removing dead batteries from the standard library

Such a great news that parser library¹ for TOML will be included in standard library from Python 3.11. So where is the simplest YAML parser library without extra deps 🤔?

Tomli is a Python library for parsing TOML. It is fully compatible with TOML v1.0.0.

A version of Tomli, the new tomllib module, will be added to the standard library in Python 3.11 via PEP 680.
