Repeating a loop 20 times

As a reminder, here's how you can use a for loop with range() to repeat something a certain number of times:

for i in range(20):
  print(i)

In this case, what we're repeating is the print(), but we could repeat anything 20 times.

Looping to use values in a collection

Here's an example of a for loop that doesn't just repeat something a number of times:

kid_ages = (3, 7, 12)
for age in kid_ages:
  print(f'I have a {age} year old kid.')

In this case we're doing this 3 times, but that's because our collection has 3 elements. Really the loop is being used to do something for each value in our collection, kid_ages .
