Here's an example: UP = 0 DOWN = 1 LEFT = 2 RIGHT = 3
keys = [0, 0, 1, 0] #up, down, left, and right keys, respectively. 0 stands for 'not pressed', 1 stands for 'is pressed'. if LEFT in keys: print True Now, it won't work, because "2" is not in the keys list. if keys[LEFT]: print True This works, because you're checking to see if the 3rd numeral in the list is positive/true.
