貪食蛇是一款經典游戲，而Python是一種高級編程語言。有沒有想過將二者結合起來呢？那么就學習一下Python貪食蛇源碼吧！

# 導入必要的模塊
import pygame
import sys
import random
# 定義一些常量
SCREEN_X = 600
SCREEN_Y = 600
FONT = 'arial'
BACKGROUND_COLOR = (192, 192, 192)
SNAKE_COLOR = (0, 255, 0)
FOOD_COLOR = (255, 0, 0)
FPS = 10
# 初始化Pygame
pygame.init()
screen = pygame.display.set_mode((SCREEN_X, SCREEN_Y))
pygame.display.set_caption('Python貪食蛇')
# 加載字體
font = pygame.font.SysFont(FONT, 24)
# 初始化蛇和食物的位置
snake = [(SCREEN_X//2, SCREEN_Y//2)]
food_pos = (random.randint(0, SCREEN_X//10)*10, random.randint(0, SCREEN_Y//10)*10)
# 初始化蛇的方向
direction = 'up'
# 游戲循環(huán)
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
# 監(jiān)聽鍵盤事件來控制蛇的方向
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_UP and direction != 'down':
direction = 'up'
elif event.key == pygame.K_DOWN and direction != 'up':
direction = 'down'
elif event.key == pygame.K_LEFT and direction != 'right':
direction = 'left'
elif event.key == pygame.K_RIGHT and direction != 'left':
direction = 'right'
# 移動蛇的位置
if direction == 'up':
snake.insert(0, (snake[0][0], snake[0][1]-10))
elif direction == 'down':
snake.insert(0, (snake[0][0], snake[0][1]+10))
elif direction == 'left':
snake.insert(0, (snake[0][0]-10, snake[0][1]))
elif direction == 'right':
snake.insert(0, (snake[0][0]+10, snake[0][1]))
# 判斷蛇是否吃到了食物
if snake[0] == food_pos:
food_pos = (random.randint(0, SCREEN_X//10)*10, random.randint(0, SCREEN_Y//10)*10)
else:
snake.pop()
# 繪制界面
screen.fill(BACKGROUND_COLOR)
for pos in snake:
pygame.draw.rect(screen, SNAKE_COLOR, pygame.Rect(pos[0], pos[1], 10, 10))
pygame.draw.rect(screen, FOOD_COLOR, pygame.Rect(food_pos[0], food_pos[1], 10, 10))
# 顯示得分
score = len(snake) - 1
text = font.render('Score: ' + str(score), True, (0, 0, 0))
screen.blit(text, (SCREEN_X-100, 10))
# 更新界面
pygame.display.update()
# 控制游戲幀率
pygame.time.Clock().tick(FPS)

以上就是Python貪食蛇游戲的源碼了。代碼使用了Pygame模塊來實現(xiàn)游戲界面和控制邏輯，同時也用到了Python語言的一些基本語法。如果你想要嘗試這個游戲，可以將代碼復制粘貼到代碼編輯器中，然后運行即可。
