[pyGame] Key Event not Working !...

[JamieVanCadsand]

Now i get this code... but it still don't work...

My Code:

import pygame
import sys
  
screen = pygame.display.set_mode((800,600))
done = False

# Change Colors in my Screen
while True:
    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            if event.key.get_pressed(K_r):
                screen.fill((255,0,0))
            if event.key.get_pressed(K_g):
                screen.fill((0,255,0))
            if event.key.get_pressed(K_b):
                screen.fill((0,0,255))

    pygame.display.update()


# Quit my Game
while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_ESCAPE:
                done = True
          
    screen.fill((0,0,0))
    pygame.display.update()

pygame.quit()
sys.exit()

I get problems with quit my game or program in pyGame and my key_inputs don't works...
What's wrong with my code, i try to use events to make the display colors of my screen
in pyGame changeble when you press R/G/B, but pyGame does'nt...

Can anyone help me to write an example and corrivate my code ?... i am an noob in python
and pyGame... but i want to learn write software with e.g. pyGame and OpenGL...

Can enyone corrivate my code ?...
Thanks, Jamie.
