Pygame animation help!!!!

[Astolfo46290]

Hi, I'm relatively new to python and I am using pygame through IDLE (in case that matters idrk) to make a smash-bros/streetfighter style game.
I am in the early stages of it's development and I'm trying to make a jumping animation, however no matter what I try the animation will not work and it is driving me INSANE!
Any help would be greatly appreciated, maybe some pointers as to what other things I could refine?
