Am I on the right track? (also simplified Kenneth Code)


Please see my code(letter.py) in the link below:


Am I on the right track? I made a simpler version of Kenneth's code as I feel his code is a bit complicated for newbies like myself, just too many things going on.

Is my understanding of how he used set, correct? I changed the lists to sets, by doing this it allowed me to use the symmetric_difference() function. But because this function compares what two things don't have in common, I reversed it with "not". By doing this it is basically saying if there are things that are the same in both sets, then end the game. Thus removing the problem with double characters like we were having when using lists?

I hope that makes sense.
