Calendar Grey February 22, 2026
Dist Fedora Esm H88
Update 3.13.12 for Fedora 43 addresses command injection issues in Python 3.13 applications with recommended installation steps.
Update to 3.13.12

Summary

Python 3.13 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 python3.13 package provides the "python3.13" executable: the reference

interpreter for the Python language, version 3.

The majority of its standard library is provided in the python3.13-libs package,

which should be installed automatically along with python3.13.

The remaining parts of the Python standard library are broken out into the

python3.13-tkinter and python3.13-test packages, which may need to be installed

separately.

Documentation for Python is provided in the python3.13-docs package.

Packages containing additional libraries for Python are generally named with

the "python3.13-" prefix.
