this line:

`print average(results)`

should use `return`

, not print.

an example of a function + function call:

```
# function declaration
def example():
return "hello world"
# function call
print example()
```

add the function calls for this exercise. Remember that functions can take parameters, and that parameters require arguments at the function call
