Security fixes for CVE-2026-4786, CVE-2026-6100
Summary
Python 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 python3.6 package provides the "python3" executable: the reference
interpreter for the Python language, version 3.
The majority of its standard library is provided in the python3.6-libs package,
which should be installed automatically along with python3.6.
The remaining parts of the Python standard library are broken out into the
python3.6-tkinter and python3.6-test packages, which may need to be installed
separately.
Documentation for Python is provided in the python3.6-docs package.
Packages containing additional libraries for Python are generally named with
the "python3.6-" prefix.
