Defining and calling functions in Python

Code is executed in the order seen.
So you can't call a function before it's defined.
Try this:
def a():
print "-a1-"
a()
def a():
print "-a2-"
a()
Or for increased fun with the letter 'a':
>>> def a():
... print "-a1-"
...
>>> def a(a=a):
... a()
... print "-a2-"
...
>>> a()
-a1-
-a2-
>>>
