THANK YOU! This is one of those things people expect you to do but never explain why you have to do it. Like, I can understand that I have to have a main function but show me why and what happens when I don't.

That is crazy as I was typing 'what is if __name__ == __main__' on the search bar, a notification popped up and it was this video. What a coincidence 😂 thanks dude

i understood this a lot more than what was discussed in the sc50 class! I need to find more simple, basic and vary beginner focused videos talking about how to structure these still though. Thanks for posting this though, it helped with a big part of the confusion on why we use these.

How are you calling myvalue as global variables at 6:03. When you use if ___name___ == '__main__' then myvalue is definitely not a global variable. You have to use *global myvalue* before defining it to make it global.

The error is not at all confusing. Its pretty clear.
