I like the way he makes videos. No pre written scripts and fixing errors on the fly. 👍👍

Hi Anthony, I often see you going for `if __name__ == "__main__": exit(main())`, but how is exit supposed to end up in the global namespace? It's present in the REPL, but it doesn't seem to be there in a regular `python3 your_module_here.py` invocation...
