Since PyCharm knows which file is "main", how can I tell it "run this project"

[Larz60+]

This section of the code:

if __name__ == '__main__':
    print(minmax(lessthan, 4, 2, 1, 5, 6, 3))    # Self-test code
    print(minmax(grtrthan, 4, 2, 1, 5, 6, 3))

is only run if starting if the module is called directly, by pressing run in PyCharm,
or from command line by typing:

python minmax.py
