Fedora 44 Python 3.11 receives crucial security fixes for multiple CVEs ensuring enhanced code reliability.
Security fixes for CVE-2026-1299, CVE-2026-0865, CVE-2025-15366 and CVE-2025-15367

Summary

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.
