Summary

Python 3.12 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 python3.12 package provides the "python3.12" executable: the reference

interpreter for the Python language, version 3.

The majority of its standard library is provided in the python3.12-libs package,

which should be installed automatically along with python3.12.

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

python3.12-tkinter and python3.12-test packages, which may need to be installed

separately.

Documentation for Python is provided in the python3.12-docs package.

Packages containing additional libraries for Python are generally named with

the "python3.12-" prefix.
