New alpha release of Python 3.15
Summary
Python 3.15 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 python3.15 package provides the "python3.15" executable: the reference
interpreter for the Python language, version 3.
The majority of its standard library is provided in the python3.15-libs package,
which should be installed automatically along with python3.15.
The remaining parts of the Python standard library are broken out into the
python3.15-tkinter and python3.15-test packages, which may need to be installed
separately.
Documentation for Python is provided in the python3.15-docs package.
Packages containing additional libraries for Python are generally named with
the "python3.15-" prefix.
