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

Answer 1

You are defining a function but never calling it. Hence you get no error but nothing happens. Add this add the end and it will work:

if __name__ == "__main__":
    main()

Answer 2

There's no such main method in python, what you have to do is:

if __name__ == '__main__':
    main()

Answer 3

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.

Answer 4

You're not calling the function. Put main() at the bottom of your code.

Answer 5

Python isn't like other languages where it automatically calls the main() function. All you have done is defined your function.

You have to manually call your main function:

main()

Also, you may commonly see this in some code:

if __name__ == '__main__':
    main()
