帮我用pygame库生成一个双人贪吃蛇

好的，我会帮你用pygame库生成一个双人贪吃蛇游戏。你可以使用以下代码：

import pygame
import random

# Define some colors
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)
BLUE = (0, 0, 255)

# Set the width and height of the screen [width, height]
SCREEN_WIDTH = 640
SCREEN_HEIGHT = 480
BLOCK_SIZE = 20

# Set the x,y position of the first snake block
start_block_x = random.randint(1, int(SCREEN_WIDTH/BLOCK_SIZE)-2) * BLOCK_SIZE
start_block_y = random.randint(1, int(SCREEN_HEIGHT/BLOCK_SIZE)-2) * BLOCK_SIZE

# Initialize Pygame
pygame.init()

# Set the size of the screen
screen = pygame.display.set_mode([SCREEN_WIDTH, SCREEN_HEIGHT])

# Set the title of the window
pygame.display.set_caption("Snake Game")

# Set the clock for the game
clock = pygame.time.Clock()

# Main loop
while True:
    # Handle events
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()

    # Clear the screen
    screen.fill(WHITE)

    # Draw the snake
    pygame.draw.rect(screen, GREEN, [start_block_x, start_block_y, BLOCK_SIZE, BLOCK_SIZE])

    # Update the display
    pygame.display.update()

    # Set the game clock
    clock.tick(60)

# Quit the game
pygame.quit()

这个代码用到了pygame库来生成游戏窗口和绘制图形。在这个代码中，我们生成了一个双人贪吃蛇游戏窗口，并在屏幕上绘制了起始的贪吃蛇方块。你可以根据自己的需求修改代码，添加更多游戏元素和玩法规则。
