Far enough, but you exchange scrolling back and forth from function to 
function with tabbing through editor tabs from file to file. I don't see 
that this is an advantage.

You also complicate calling functions. Instead of:


def parrot():
    spam()
    ham()
    cheeseshop()


you need:


from spam import spam
from ham import ham
from import cheeseshop

def parrot():
    spam()
    ham()
    cheeseshop()


This is not an advantage!
