Python 3.12.0 Released! How to Install via Ubuntu PPA

Python 3.12.0 final was officially announced this Monday! Ubuntu LTS can easily install it from PPA.

New features in Python 3.12.0:

• More flexible f-string parsing, allowing many things previously disallowed.
• Python-level API for the buffer protocol
• New API for monitoring Python programs running on CPython at low cost.
• Per-Interpreter Global Interpreter Locks
• Support for the Linux perf profiler to report Python function names in traces.
• New type annotation syntax for generic classes
• New decorator typing.override() in the typing module.

The new Python release also removed a few deprecated modules, including smtpd and distutils. For Ubuntu 22.04, Ubuntu 20.04, it causes a broken pip. As a workaround, you need to manually install pip for Python 3.12.

For Ubuntu 22.04, Ubuntu 20.04, and their derivatives such as Linux Mint 21, the Deadsnakes PPA has made the packages for all supported CPU architecture types: amd64, arm64/armhf, ppc64el, and s390x.
