So far, the code generates a deck, creates hands for every player, and then shows the player his/her cards. Then the player is asked which computer player he/she wants to target as well as the rank of cards.

Then I tried converting "hit" into another code before entering the definition, changing it while inside, then converting it back before returning it but that also seems to do nothing, and I still get the same issues.

You have "else" lined up with "for".

In Python a "for" loop can have an "else" clause, which is run if it 
didn't "break" out of the loop but finished.
