Python provide while loops for more fine-grain control, and a protocol
so *reuseable* iterators can plug into for loops. Duncan showed you
both.  If you *need* a doubling loop variable once, you probably need
one more than once, and the cost of the doubling generator is amortized
over all such uses.  Any Python proprammer should definitely know how to
write such a thing without hardly thinking.  We can squeeze a line out
of this particular example:

def doubling(value, limit):
   while value <= limit:
     yield value
     value += value

Shouldn't the upper limit be exclusive in order to be Pythonic?

Yes, and perhaps I could have mentioned that, but the OP wanted a port 
of the C construct.
