What is Python's Main Function Useful For? 

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.

I like this man how he starts his videos and his explanaition. he looks fynny but serious. i expect more on python GUI

I'm from Harvard CS50, intro to python programming, this video has helped me a lot. Thanks

Something confusing to new learners is when you use .py names that are duplicative of non dynamic syntax. Calling the .py "main" when the if statement is not referring to the .py named main causes confusion. A new user will see that and attempt to change '__main__' to reference the .py they are trying to call the functions from. Otherwise, very good video.

Thanks :) I just counted on that I could find a video with you explaining this :D

There is just one word to describe you guy : AWESOME.

protect this man at all costs

Best explanation of this in Yt

great help man!! appreciate it !!

Shouldn't the if __name__ == "__main__" expression be only inside the "main" script? Not in "mylibrary"...

beautiful, thanks a lot!!!

Great tutorial. I do have a question. Don’t you need the keyword “global” to turn a variable into a global variable ?

What theme are you using in pycharm ,bro 🤔

grate job

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 have done a lot of reading and practicing in Python never could understand the dunder thing was and now it finally clicked for me. Thanks, man!

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.

BRILLIANT! After watching at least 10 other tutorials, I FINALLY undersand this concept. Great teaching skills and great style, keep it up ;)

Bruh, are you reading my mind or something? Just got lectured on the Python Subreddit yesterday for not using Main on a script I posted there, lmao

I’ve watched a few videos about this and by far you have the most clear understandable explanation

why do if __name__ == '__main__': not throw valueerror forexpecting else:

Bro, there are two possibilities, either you’re fucking genius teacher or others are terrible craps doing it. Whatever the answer is, as many others here i finally understood this concept after a few hours of unsuccessful researches.

at 6:09, `myvalue` was still undefined even though it was globally defined. why was it so?

YOU'RE TOO GREAT buddy, thanks for dissecting these python notions like that..

Dude! WTH dude! thank ****! much love bro thanks

Can you make video about Jython(Java + Python)

Awesome! I had needed this in my project and I didn't know how to do it... Thanks again!

my mind just exploded, I see lots of people using it but never had seen someone explaining it, thanks a lot!

The best explaination I could find! Thanks a lot

excellent video. Tweeted.

for all main part lol

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.

Finally understood why we use it! Thanks Man!

Thank you s so much!

can you do some tutorials of pillow?

You are awesome!😃

Great video.

Thanks, I watched 5 other RU-vid videos on this topic and your video explained this topic the best.

yeah I agree with other comment - saw other videos on this topic and I think your explanation was best. thanks.

Do the Nvim tutorial of the COC implementation or the new LSP of the Neovim 0.5 :(

Thx_.

so variable can't define as globally, but can define in local. And no error?

Very nice and detailed explanation...thank you so much

Great, help me to understand. Hugs from Brasil

Thank you this was the best explanation for this topic!

Exactly the answer I was after, thanks 👍👍

Thanks so useful! And so easy to understand

This video helped me a lot!! Thank you!

This was really interesting. Thanks!

please do a Cython tutorial , and a question , is Cython more practical to use than CPython?

You are the best teacher I have found. You are a genius. Thank you

Thank you so much!

Great explanation 🔥

Thanks for this! :)
