PyGame运行报错：TypeError: draw_window()缺少red和yellow参数

错误原因很明确：你定义的draw_window(red, yellow)函数声明需要接收red和yellow两个参数，但在main函数的循环中调用draw_window()时，没有传递这两个必要的Rect对象。

只需要修改main函数里的调用语句，把red和yellow作为参数传入即可：

def main():
    red = pygame.Rect(100, 300, SPACESHIP_WIDTH, SPACESHIP_HEIGHT)
    yellow = pygame.Rect(700, 300, SPACESHIP_WIDTH, SPACESHIP_HEIGHT)

    clock = pygame.time.Clock()
    run = True
    while run:
        clock.tick(FPS)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False

        red.x += 1
        # 传入red和yellow参数
        draw_window(red, yellow)

    pygame.quit()

修改后的完整代码：

import pygame
import os

WIDTH, HEIGHT = 900, 500
WIN = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption('Simple Game')

WHITE = (255, 255, 255)

FPS = 60
SPACESHIP_WIDTH, SPACESHIP_HEIGHT = 55, 40

YELLOW_SPACESHIP_IMAGE = pygame.image.load(
    os.path.join('Assets', 'spaceship_yellow.png'))

YELLOW_SPACESHIP = pygame.transform.rotate(pygame.transform.scale(
    YELLOW_SPACESHIP_IMAGE, (SPACESHIP_WIDTH, SPACESHIP_HEIGHT)), 90 )

RED_SPACESHIP_IMAGE = pygame.image.load(
    os.path.join('Assets', 'spaceship_red.png'))

RED_SPACESHIP = pygame.transform.rotate(pygame.transform.scale(
    RED_SPACESHIP_IMAGE, (SPACESHIP_WIDTH, SPACESHIP_HEIGHT)), -90)

def draw_window(red, yellow):
    WIN.fill(WHITE)
    WIN.blit(YELLOW_SPACESHIP, (yellow.x, yellow.y))
    WIN.blit(RED_SPACESHIP, (red.x, red.y))
    pygame.display.update()


def main():
    red = pygame.Rect(100, 300, SPACESHIP_WIDTH, SPACESHIP_HEIGHT)
    yellow = pygame.Rect(700, 300, SPACESHIP_WIDTH, SPACESHIP_HEIGHT)

    clock = pygame.time.Clock()
    run = True
    while run:
        clock.tick(FPS)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False

        red.x += 1
        draw_window(red, yellow)

    pygame.quit()


if __name__ == "__main__":
    main()
