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

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 in a number and returns that number multiplied by 4 would look like:

def mult_by_four(number): multiplied = number * 4 return multiplied

And this would produce output like:

>>> mult_by_four(10) 40 >>> mult_by_four(0) 0 >>> mult_by_four(-1) -4

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