The main unit is the program (the one that starts with the keyword  
'program' instead of 'unit', and has no interface). But if you don't know  
what a program is, explaining the analogy is pointless.

Just remember to put a guard like this:

if __name__ == '__main__':

around anything you don't want executed when the code is imported (as  
opposed to being run as a script/program)
