The main() function appears to not work [duplicate]

You’ve not called your main function at all, so the Python interpreter won’t call it for you.

Add this as the last line to just have it called at all times:

main()

If you use the commonly seen:

if __name__ == "__main__":
    main()

It will make sure your main method is called only if that module is executed as the starting code by the Python interpreted, more about that is discussed here: What does if __name__ == “__main__”: do?

If you want to know how to write the best possible ‘main’ function, Guido van Rossum (the creator of Python) wrote about it here.
