Python Functions AFTER code

Question

Is there a way (without putting the function in a separate file) to define the content of a function after the bulk of my code? Sort of like C where you define prototypes and put the body later on in the file.

Ex;

blah blah blah
functionCall(arg)
blah blah blah

def functionCall(arg):
   blah blah blah

Answer 1

Yes. Instead of

blah blah blah
functionCall(arg)
blah blah blah

def functionCall(arg):
    blah blah blah

Do

def main():
    blah blah blah
    functionCall(arg)
    blah blah blah

def functionCall(arg):
    blah blah blah

if __name__ == '__main__':
    main()

The if __name__ == '__main__': bit is mostly unrelated to the topic of the question; it just prevents the main from running if this file is imported as a module.
