Nicholas, the method is not called unless you add parentheses, e. g:

>>> "1".isdigit # a bound method *always* True in a boolean context
<built-in method isdigit of str object at 0x402711c0>
>>> "1".isdigit() # True only if all chars in the string are digits

Another observation. buttonx need not be an attribute.

for y in range(4):
   buttonx = ...

will just work as well, provided you don't want to keep a reference of the
last button created in the loop.
