Function name not defined

I have a pice of code which looks like this 

if __name__ == "__main__":
    main()


def main():
    print("hello")

However, when I try to run this code I get the error

NameError: name 'main' is not defined

Have I not defined the name in the first line of the function "def main()"?

You should define main before call it

def main():
    print("hello")

if __name__ == "__main__":
    main()

Yes, but Python hasn't executed that definition yet. Put the function definition before the call.
