THIS IS FAKE DEMO DATA

In Python it's possible to attach an else clause to a for loop. The code under the else block will be run when the iterable is exhausted (there are no more items to iterate over). Code within the else block will not run if the loop is broken out using break.

Here's an example of its usage:

numbers = [1, 3, 5, 7, 9, 11]

for number in numbers:
    if number % 2 == 0:
        print(f"Found an even number: {number}")
        break
    print(f"{number} is odd.")
else:
    print("All numbers are odd. How odd.")
