Get better at visually distinguishing between varying length sequences of zeros.

"""
Small program to help develop the ability to count the number of zeros in a
number very quickly.

An upgrade to this would be the following: Randomly generate a number with
multiple long repeating sequences of integers. Then ask the user for the length
of the longest repeating sequence within the number.
