For a bit more performance, use a number, like 0 or 1.
Using None requires a name lookup.

>>> def check_none(r):
...     for c in r:
...             None == None
...
>>> def check_one(r):
...     for c in r:
...             1 == 1
...
>>> import time
>>> r = range(1000000)
>>> t1=time.time();check_none(r);t2=time.time()
>>> t2-t1
6.01800501347
>>> t1=time.time();check_one(r);t2=time.time()
>>> t2-t1
2.72878599167
