Can someone explain how pygame.transform.chop works? The way I would think it works is you put in the coords and size of the section of image you want to chop, then you blit it to a surface, but when I tried to use it it did this
2000000
0111111
0111111
Imagine the picture is the numbers. I was trying to take out the 2 and blit it to a surface, but what the program did was cut out the 2 and the 0s and then blit the 1s. Is it just the fact that I am using an online IDE, or is that not how pygame chop works?

As you already discovered, the chop works at the opposite of what you need. You select a cross to remove from an image and the remaining areas are glued together in a new image.
I drew to pictures to better explain what I mean:
If you select a corner, you will observe exactly the behaviour you described (area color meanings are the same of the picture above):
To select a rectangular surface of an image, mainly to get sprites from a spritesheet, you need to use the pygame.Surface.subsurface method. It define a child image of your main one ready to be blitted on a new surface or used as is.
Warning Changes to the main surface or to the subsurface will be reflected on the other one.
thanks for the explanation!
I have used pygame.transform.chop before and it usually takes in a Rect object for defining the section to be chopped. From your description it appears the blitting process might not align with your expectations.
