Answer 1

What error? there's a `set` of string in the code bit not a `list`. Are you sure that was the code in question?

Actually, I'm not clearly understanding your question. Perhaps you can elaborate further on it?

Answer 2

Sanjay Kamath ,

there is a small typo in your set, have a look at the second 'pen' since there is an enclosed comma in the last string.

ppap={"pen","pineapple","apple",",pen"}
^^^

for this case, the length will be 4. if you correct the typo, the length will be 3.
