Because you need to define things *before* you use them the first time. 
This is not to be confused with forward-declarations, as they are needed 
in C for example - in python you can do


def foo():
    bar()

def bar():
    foo()


(resulting in an endless loop of course)

But you can't do


def foo():
    bar()

foo() # this will fail

def bar():
    foo()
