[PyGame] Need Help With My PYgame Script

[Windspar]

1. indentation is off. KEYUP will never be called in KEYDOWN.
You should check into keys states.

# Keys state. still need pygame.event.get() or pygame.event.pump() before getting states.
keyspressed = pygame.key.get_pressed()
if keyspressed[pygame.LEFT]:
    x -=5
if keyspressed[pygame.RIGHT]:
    x += 5
# etc

2. pygame has builtin colors

import pygame
print(pygame.color.THECOLORS.keys())
print()
print(pygame.Color('red'))
