Restructure the code for some examples according to PEP8 guidelines?

Hey there! A really neat repository!

I was browsing through the code and noticed in some examples that you've written entire blocks of code within if __name__ == __main__ block. I am willing to restructure it, it's possible to import the functions you've put within the if __main__ == __name__: blocks if they were outside it.

Let me know what you think 😁

Sure go ahead, I will do the code review.
