Python 2.

Python 2 should not be used. Period. Fix: Convert all code. @ternus

Are you asking how to convert your code to python 3?

[taitep]

no, i just do not think i could convert all code of the repo.

There isn't much to do in order to make the codes compatible in Python 3.x

In snake.py and snake2.py the only thing that's causing issues is GRID_WIDTH and GRID_HEIGHT being interpreted as float. This causes issues with the randint function call as it expects two integers as input.

To fix this cast the value to int:

GRID_WIDTH = int(SCREEN_WIDTH / GRIDSIZE)
GRID_HEIGHT = int(SCREEN_HEIGHT / GRIDSIZE)

As for lunarlander.py there are some small issues in the load_image function. The first issue being the way exceptions are handled along with the print of that error message.

So you'd have to change

    except pygame.error, message:
        print 'Cannot load image:', fullname
        raise SystemExit(message)

to

    # Catch the exception and assign it to the "error" variable
    except pygame.error as error:

        # Here you just need the parenthesis
        print('Cannot load image: ', fullname)

        # Throw the exception with the error message
        raise SystemExit(error)

The second one is more of a warning because the colorkey in the load_image function is compared to -1 with is instead of ==. If you're curious on what the difference is, check this out

So you'd have to change

if colorkey is -1:

to

if colorkey == -1:
