A recursive function is a function that calls itself.  For
instance:

>>> def silly_print_string(s):
... 	if len(s) > 0:
... 		print s[0]
... 		silly_print_string(s[1:])
... 		
>>> silly_print_string("test")
t
e
s
t
>>> silly_print_string("another test")
a
n
o
t
h
e
r
 
t
e
s
t

this recursive function prints the first letter of the string and
then calls itself with the remainder of the string.  This
function definition may also give you a hint.
