Odometer

An odometer is the meter in a car that registers how many miles (or kilometers) the car has traveled in its lifetime. It begins at

000000

and every mile that it travels, the counter ticks up by one:

000001

… then

000002

and so on.

Write a program odometer.py that uses 4 nested loops to print out a four-digit odometer. Use one separate loop for each digit in the odometer:

0 0 0 0

^ ^ ^ ^
| | | |
i j k l

It may be helpful for you to print out the numbers using print formatting:

print("{0:1d}{1:1d}{2:1d}{3:1d}".format(i,j,k,l))

You may wish to slow the odometer down a little by using the time module and having it sleep between ticks:

import time
.
.
.
time.sleep(0.2)     # sleeps for 0.2 seconds

You might also want to clear the screen between each tick:

import os
.
.
.
os.system("clear")      # on Apple machine
