A function has to be defined before a call to it is executed. You can think
of the "def" statement as assigning the functional meaning to the function
name. If calls to the function appear inside other functions you will be OK,
as functions don't get executed when they are compiled.

For this, and other, reasons, the main part of a module is often coded as a
"main()" function, and the code finally executed with

if __name__ == "__main__":
    main()

at the end of the script. The other reasons include making it easy to run
tests on a module really designed to be imported, but it's a good paradigm.
