key input pseudo code

gistfile1.txt

# This garbage code is just here to demonstrate an idea :)

import key  # We're pretending this is a module that can tell us when a key is pressed.

# Pretend these are RGB values. Also you would probably want a multi-dimensional array to check
#   but again, let's keep it simple here.
light1 = [0, 0, 0]
light2 = [0, 0, 0]
light3 = [0, 0, 0]

keyPressed = false

while true:  # Just loop forever (usually a bad idea)
    keyPressed = key.read()
    if keyPressed is true:
        light1[0] += 1  # We turn up the value of Red in each light
        light2[0] += 1
        light3[0] += 1
    
    # Either way, display the lights
    light1.display()
    light2.display()
    light3.display()
