FEDORA-2026-a0b1d4b9fa

--------------------------------------------------------------------------------

Name        : python3.11
Product     : Fedora 42
Version     : 3.11.15
Release     : 2.fc42
URL         : https://www.python.org/
Summary     : Version 3.11 of the Python interpreter
Description :
Python 3.11 is an accessible, high-level, dynamically typed, interpreted
programming language, designed with an emphasis on code readability.
It includes an extensive standard library, and has a vast ecosystem of
third-party libraries.

The python3.11 package provides the "python3.11" executable: the reference
interpreter for the Python language, version 3.
The majority of its standard library is provided in the python3.11-libs package,
which should be installed automatically along with python3.11.
The remaining parts of the Python standard library are broken out into the
python3.11-tkinter and python3.11-test packages, which may need to be installed
separately.

Documentation for Python is provided in the python3.11-docs package.

Packages containing additional libraries for Python are generally named with
the "python3.11-" prefix.
