    summary: Python programming language, version 3.6
    description: |-
        This module gives users access to the internal Python 3.6 in RHEL8, as
        well as provides some additional Python packages the users might need.
        In addition to these you can install any python3-* package available
        in RHEL and use it with Python from this module.

            python-PyMySQL:
                rationale: Python adapter for the MySQL/MariaDB databases
                # PyMySQL [0] vs. mysqlclient-python [1]
                # - PyMySQL was originally chosen for the rh-python35 RH
                #   Software collection due to the opinion that maintaining
                #   mysqlclient-python would take much more resources (bad
                #   communication with upstream, backward incompatibilities in
                #   test suite, ...)[2]. PyMySQL was deemed the better
                #   alternative.
                # - When creating this module, this decision was reassessed,
                #   because mysqlclient-python seems to be faster than PyMySQL,
                #   but the choice was reaffirmed due to the customers already
                #   being familiar with PyMySQL from the abovementioned RHSCLs,
                #   and due to wider popularity of PyMySQL upstream.[3]
