--------------------------------------------------------------------------------
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.
