I'm not sure if I understand __iter__. You use it to
create an object that iterates through itself using a
next menthod ?
class Squares:
def __init__(self, start, stop):
self.value = start - 1
self.stop = stop
def __iter__(self):
return self
def next(self):
if self.value == self.stop:
raise StopIteration
self.value += 1
return self.value ** 2
>>> from iters import Squares
>>> for i in Squares(1, 5):
... print i,
...
1 4 9 16 25
