[Baypiggies] len(iterable)

[Shannon -jj Behrens]

I have an iterable, and I want to find out how long it is.  I don't
care if it consumes the iterable.  Furthermore, I know the iterable is
not infinite.  Consider:

>>> len((i for i in xrange(10)))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: object of type 'generator' has no len()

It makes sense that len() not be defined, but I can't seem to find a
simple count function.  Of course, I can write one, but it seems like
it should exist in itertools or something.  (By the way, the count
function in itertools is something completely different.)

Thanks,
-jj
