尝试在这些命令之前放置4个空格或一个选项卡，并获取

import pygame
pygame.init()
# display size
width = 1800
height =1000
# colors
black = (0, 0, 0)
blue = (0, 0, 255)
white = (255, 255, 255)
green = (0, 255, 0)
red = (255, 0, 0)
aqua = (1, 255, 255)
# main display
gamedisplay = pygame.display.set_mode((width, height))
pygame.display.set_caption('Race Game')  # the
clock = pygame.time.Clock()
# the car image
carImg = pygame.image.load('myCar.png')
# car
def car(x, y):
    gamedisplay.blit(carImg, (x, y))
x = (width * 0.45)
y = (height * 0.8)
# events
crashed1 = False
x_change = 0
while not crashed1:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            crashed1 = True

        if event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT or pygame.K_RIGHT:

    print(event)
    gamedisplay.fill(white) 
    car(x, y)
    pygame.display.update()
    clock.tick(120)
pygame.quit()
