im fairly new to coding, and i just finished writing up this code for a centroid calculator, and i was just curious to have more advance coders have a look at this and critique me on my style or suggest any better ways to getting to the end.

what could i do to shorten it??

what could i do to maybe make it more readable?( i had to leave comments on everysingle line for teacher)

im open so just let me know your opinions on one of my first programs.

thank you
