Need help with introduction to computer science .append question

Im not sure what I am doing wrong here… I would like my function to be looped 3 times to add the last two items on the list together and append them to the list. it seems to only do this once even though I have it to repeat in range 3. Why is this working on other things but not when using .append.

Thanks in advance!

Double check the indentation on your return statement. Also, return doesn’t need parens.

It worked! Thanks for the help! So close :sweat_smile:
