Name : python2.7 Product : Fedora 33 Version : 2.7.18 Release : 15.fc33 URL : https://www.python.org/ Summary : Version 2.7 of the Python interpreter Description : Python 2 is an old version of the language that is incompatible with the 3.x line of releases. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features have finally been removed in the 3.x line.
Note that Python 2 is not supported upstream after 2020-01-01, please use the python3 package instead if you can.
This package also provides the "python2" executable.
