[pyGame] Key Event not Working !...

[Mekire]

On an unrelated note of style, switch on a dictionary rather than a big if/elif/else block:

import sys
import pygame as pg
   

COLORS = {pg.K_r : pg.Color("red"),
          pg.K_g : pg.Color("green"),
          pg.K_b : pg.Color("blue")}


screen = pg.display.set_mode((800,600))
done = False


while not done:
    for event in pg.event.get():
        if event.type == pg.QUIT:
            done = True
        elif event.type == pg.KEYDOWN:
            if event.key == pg.K_ESCAPE:
                done = True
            elif event.key in COLORS:
                screen.fill(COLORS[event.key])                  
    pg.display.update()


pg.quit()
sys.exit()
