Add Return Statement

00:00 I pasted a code from the exercise into the IDLE editor. So there is an on_the_shelf() function, which contains a list named shelf_cookies and that contains the strings, Peanut and Chocolate.

00:13 There is also the under_the_sofa() function, which contains a sofa_cookies list, and this list contains the strings Oat and Salted Caramel.

00:25 And then you have the cookies list, which is currently empty, and the print() function call, which takes cookies. And this should print an empty list so let’s try that out.

00:35 Save and run the file.

00:39 And indeed the cookies list right now is empty. And to actually get the cookies, we need to do a few things. One thing is currently both functions don’t return anything when we are calling the on_the_shelf() function or the under_the_sofa() function, None would be returned.

01:00 However, we want the lists returned. So let’s add two return statements with the cookies lists. I start with the on_the_shelf() function and in the last line of the function body, I add return shelf_cookies.

01:16 And I’ll do a similar thing with the under_the_sofa() function. So in the last line of the function body, I add a return statement, which returns, in this case, sofa_cookies.

01:31 Now both functions return something, but we need to add it to the list. Let’s do this in the next lesson.
