本文實例為大家分享了python貪吃蛇游戲的具體代碼，供大家參考，具體內容如下

貪吃蛇游戲截圖：

首先安裝pygame，可以使用pip安裝pygame：

pip install pygame

運行以下代碼即可：

#!/usr/bin/env pythonimport pygame,sys,time,randomfrom pygame.locals import *# 定義顏色變量redColour = pygame.Color(255,0,0)blackColour = pygame.Color(0,0,0)whiteColour = pygame.Color(255,255,255)greyColour = pygame.Color(150,150,150)# 定義gameOver函數def gameOver(playSurface): gameOverFont = pygame.font.Font('arial.ttf',72) gameOverSurf = gameOverFont.render('Game Over', True, greyColour) gameOverRect = gameOverSurf.get_rect() gameOverRect.midtop = (320, 10) playSurface.blit(gameOverSurf, gameOverRect) pygame.display.flip() time.sleep(5) pygame.quit() sys.exit()# 定義main函數def main(): # 初始化pygame pygame.init() fpsClock = pygame.time.Clock() # 創建pygame顯示層 playSurface = pygame.display.set_mode((640,480)) pygame.display.set_caption('Raspberry Snake') # 初始化變量 snakePosition = [100,100] snakeSegments = [[100,100],[80,100],[60,100]] raspberryPosition = [300,300] raspberrySpawned = 1 direction = 'right' changeDirection = direction while True: # 檢測例如按鍵等pygame事件 for event in pygame.event.get():  if event.type == QUIT:  pygame.quit()  sys.exit()  elif event.type == KEYDOWN:  # 判斷鍵盤事件  if event.key == K_RIGHT or event.key == ord('d'):   changeDirection = 'right'  if event.key == K_LEFT or event.key == ord('a'):   changeDirection = 'left'  if event.key == K_UP or event.key == ord('w'):   changeDirection = 'up'  if event.key == K_DOWN or event.key == ord('s'):   changeDirection = 'down'  if event.key == K_ESCAPE:   pygame.event.post(pygame.event.Event(QUIT)) # 判斷是否輸入了反方向 if changeDirection == 'right' and not direction == 'left':  direction = changeDirection if changeDirection == 'left' and not direction == 'right':  direction = changeDirection if changeDirection == 'up' and not direction == 'down':  direction = changeDirection if changeDirection == 'down' and not direction == 'up':  direction = changeDirection # 根據方向移動蛇頭的坐標 if direction == 'right':  snakePosition[0] += 20 if direction == 'left':  snakePosition[0] -= 20 if direction == 'up':  snakePosition[1] -= 20 if direction == 'down':  snakePosition[1] += 20 # 增加蛇的長度 snakeSegments.insert(0,list(snakePosition)) # 判斷是否吃掉了樹莓 if snakePosition[0] == raspberryPosition[0] and snakePosition[1] == raspberryPosition[1]:  raspberrySpawned = 0 else:  snakeSegments.pop() # 如果吃掉樹莓，則重新生成樹莓 if raspberrySpawned == 0:  x = random.randrange(1,32)  y = random.randrange(1,24)  raspberryPosition = [int(x*20),int(y*20)]  raspberrySpawned = 1 # 繪制pygame顯示層 playSurface.fill(blackColour) for position in snakeSegments:  pygame.draw.rect(playSurface,whiteColour,Rect(position[0],position[1],20,20))  pygame.draw.rect(playSurface,redColour,Rect(raspberryPosition[0], raspberryPosition[1],20,20)) # 刷新pygame顯示層 pygame.display.flip() # 判斷是否死亡 if snakePosition[0] > 620 or snakePosition[0] < 0:  gameOver(playSurface) if snakePosition[1] > 460 or snakePosition[1] < 0:  for snakeBody in snakeSegments[1:]:  if snakePosition[0] == snakeBody[0] and snakePosition[1] == snakeBody[1]:   gameOver(playSurface) # 控制游戲速度 fpsClock.tick(5)if __name__ == "__main__": main()
