python贪吃蛇小游戏代码

以下是一个简单的 Python 贪吃蛇小游戏代码：

# 初始化 Pygame
pygame.init()

# 游戏窗口大小
WINDOW_WIDTH = 600

# 定义颜色
BLACK = (, , )

GREEN = (, 255, )
BLUE = (, , 255)

# 创建游戏窗口
game_window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption('贪吃蛇小游戏')

# 定义蛇的初始位置和大小
snake_position = [100, 50]
snake_body = [[100, 50], [90, 50], [80, 50]]

                 random.randrange(1, (WINDOW_HEIGHT // 10)) * 10]

# 定义初始方向

# 定义游戏时钟

# 定义字体
font_style = pygame.font.SysFont(None, 50)


# 显示分数
