Code Challenge: Loops
Introduction
This lesson will help you review Python functions by providing some challenge exercises involving loops.
As a refresher, function syntax looks like this:
def some_function(some_input1, some_input2): … do something with the inputs … return output
For example, a function that prints all odd numbers in a list would look like this:
def odd_nums(lst): for item in lst: if item % 2 == 1: print(item)
And this would produce output like:
>>> odd_nums([4, 7, 9, 10, 13]) 7 9 13
When you’re ready to do this series of short function challenges, continue on to the rest of the lesson!
