You probably don't really want to write code like this in Python. How
about:
class Counter(object):
def __init__(self, start=0):
self.value = start
def incr(self):
self.value += 1
counter = Counter(1)
counter.incr()
print counter.value
Or you can likely get everything you need from itertools.count.
