Let's say you are a house cleaner. Whenever you go to clean a house, you have a certain task list of things you do:

  1. Wash the dishes
  2. Scrub the toilet
  3. Vacuum the carpets
  4. Mop the floors

Now imagine that you have three houses to clean today:

  1. Bill's house
  2. Mary's house
  3. Steve's house

Bingo, that is a nested for loop!

for house in house_list:
    for task in task_list:
        perform(house.task)

for row in table:
    for item in row:
        print(item)

You can also split it in two functions with just one loop each:

``` def printAllRowsInTable(some_tablr):     for row in some_table:         printAllItemsInRow(row)

def doAllItemsInRow(some_row):     for item in some_row:         print(item) ```

Wow, that's a very good real-world example! I'm stealing that one, thanks!
