itertools.count

Describing itertools.count(start, step)

• The count function is used to output consecutive numbers
• It returns an iterator of evenly spaced numbers
• The first evenly spaced number is based on start
• The space between each number is based on step
• The count function is considered an infinite iterator
• This is because the iterator generates numbers without any finite end boundary (values go off to infinity)

>>> nums = count(10, 2)

>>> for i in range(5):
...     print(next(nums))
