Name : python3.13 Product : Fedora 43 Version : 3.13.12 Release : 2.fc43 URL : https://www.python.org/ Summary : Version 3.13 of the Python interpreter Description : 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.
