calling functions style question

The difference becomes clear when you import your program into another
program (or the command line python editor). __name__!='__main__' when
you import, so the functions will not be called if they're inside the
block. This is why you see this block so often at the end of scripts;
so that the script runs its main functions when called as a standalone
program, but you can also import the code and do something with it
without setting off those functions.
