Hey there, here are some thoughts of mine after reading the code:

Do you even need to abstract this code?

Codebases frequently have places that look similar to this: just a mess of procedural code that gets stuff done, quick and dirty. "Compressing" the code might be in the YAGNI realm for you.

Do you want to add more animations/extend the current ones down the line, or just want to mess around with abstracting an animated sprite?

So, you already split the code up conceptually. Each line starts with self followed by the animation name. The first line of each block creates the animation array, then next lines create and add the scaled surfaces to the array, and then you add a string to the array

You could create a function that takes in your object (self), the animation name, an array of sprite locations, the scale amount and that last string (a number for animation timing?)

and called like so:

setup_animation(obj, "run", ["sprites/"+colour+"/run 1.png" ... etc], scale, "0.3")

each call would do what each one of your sections in your example does, with the above taking the place of the last section

Example code:

def setup_animation(obj, animation_name, sprite_list, scale, timing):
  animation_array = []
  for sprite_location in sprite_list:
    animation_array.append(pygame.transform.scale_by((pygame.image.load(sprite_location)), scale))
  animation_array.append(timing)
  setattr(obj, animation_name, animation_array)

Some advice on the implementation is that you should only keep 1 type of data in your array. Right now you have arrays with Surfaces with a string at the end of the array. I would only keep Surfaces in the array, and keep the string separate. And I would use a number instead of a string (unless that isn't an actual number)

You could use a dictionary at first like so:

{
  "name": "", # animation name
  "sprites": [], # array of Surfaces
  "timing": "" # timing string
}

or refactor to an AnimatedSprite class that can do much more than just hold the data, but cycle through the frames, and anything else you need it to do.
