#!/usr/bin/python3 import pygame #import file colors.py pygame.init()  white = (255,255,255) #game display display_width = 800 display_height = 600  gamedisplay = pygame.display.set_mode((display_width,display_height)) pygame.display.set_caption('sound soul') clock = pygame.time.clock()  #characterimg = pygame.image.load(' ')  #functions  #start of game loop def game_loop():     x = (display_width * 0.45)  y = (display_height * 0.8)  def character_display(x,y):     gamedisplay.blit(characterimg,(x.y))  x_move = 0 y_move = 0  dead = false if dead == false:     gameexit = false elif gameexit == true:     pygame.quit()     quit() #logic loop while not dead:      event in pygame.event.get():         if event.type == pygame.quit:             dead = true         #mechanics         if event.type == pygame.keyup:             if event.key == pygame.keyup:                 y_move = 5             elif event.key == pygame.keydown:                 y_move = -5          if event.type == pygame.keydown:              if event.key == pygame.keyup or pygame.keydown:                  y_move = 0          if event.type == pygame.k_left:             if event.key == pygame.k_left:                 x_move = 5             elif event.key == pygame.k_right:                 x_move = -5          if event.type == pygame.k_right:              if event.key == pygame.k_left or pygame.k_right:                  x_move = 0     x += x_move     y += y_move      gamedisplay.fill(white)     #character-display(x,y)     #frames per second     pygame.display.update()     clock.tick(30)  pygame.quit() quit()
