Please take a look if you can tell me what am I doing wrong here. I want to check each list word by word if the word is not repeated in the same list it should be appended to a 'newlist'.

The first thing I note in looking at this is that the second loop will
run AFTER the first loop completes, not for each step of the loop,
because you outdented the code.

Also, you unconditionally add the word, and THEN check if it is in the list.
