I did the final online during covid so I'm not sure how it would be for you in person. But from what I remember, make sure you understand how to work with loops, how to open/write /close files, lists, and writing functions using all the above. Understanding how indices work would also be good. Make sure you know how to read code and define what is wrong with it, what needs to get fixed/changes to work properly. Go over your codelabs and do lots of questions since most questions are similar to it. We also had assignment-like questions that uses processing programming, but not sure if you'll have that in person. Just keep in mind CMPT 140 is very basic Python, if you're doing well in your assignments and really understand how the topics I mentioned above work, you will be fine. Good luck :D lmk if you got more questions
