In the code above, we added the statement “number1 + number2”. This is the code which actually adds the numbers supplied. Now, let’s store the value of number1 + number2 in a variable named total.

At this point, we’ll use another keyword, “return”. The return keyword exits a function. It tells Python “Hey, this is the end of this function” and optionally returns a value (the result of the action carried out by the function). If you don’t include a return statement in your function, it’ll return “None”. Let’s practice this. We’ll add a return statement to our “add_numbers” function to return the value of our variable, “total”.
