Code Challenge: Control Flow
Introduction

This lesson will help you review Python functions by providing some challenge exercises involving control flow.

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 takes a number and checks to see if it is greater than ten would look like this

def greaterThanTen(number): if number > 10: return True else: return False

And this would produce output like:

>>> greaterThanTen(20) True >>> greaterThanTen(-10) False >>> greaterThanTen(10) False

When you’re ready to do this series of short function challenges, continue on to the rest of the lesson!
