Python 文本版贪吃蛇游戏代码

当然可以帮您编写一个贪吃蛇游戏的文本版！以下是一个基本的文本版贪吃蛇游戏的 Python 代码示例：

import random
import msvcrt

# 定义游戏区域尺寸
WIDTH = 20
HEIGHT = 10

# 定义蛇身和食物的符号
SNAKE_SYMBOL = '■'
FOOD_SYMBOL = '★'

# 定义蛇类
class Snake:
    def __init__(self):
        self.body = [(WIDTH // 2, HEIGHT // 2)]
        self.direction = 'right'

    def move(self):
        x, y = self.body[0]
        if self.direction == 'up':
            y -= 1
        elif self.direction == 'down':
            y += 1
        elif self.direction == 'left':
            x -= 1
        elif self.direction == 'right':
            x += 1
        self.body.insert(0, (x, y))
        self.body.pop()

    def change_direction(self, new_direction):
        if new_direction == 'up' and self.direction != 'down':
            self.direction = new_direction
        elif new_direction == 'down' and self.direction != 'up':
            self.direction = new_direction
        elif new_direction == 'left' and self.direction != 'right':
            self.direction = new_direction
        elif new_direction == 'right' and self.direction != 'left':
            self.direction = new_direction

    def check_collision(self):
        x, y = self.body[0]
        if x < 0 or x >= WIDTH or y < 0 or y >= HEIGHT or (x, y) in self.body[1:]:
            return True
        return False

    def draw(self):
        for y in range(HEIGHT):
            for x in range(WIDTH):
                if (x, y) == self.body[0]:
                    print(SNAKE_SYMBOL, end='')
                elif (x, y) in self.body:
                    print('O', end='')
                else:
                    print(' ', end='')
            print()

# 定义食物类
class Food:
    def __init__(self):
        self.x = random.randint(0, WIDTH - 1)
        self.y = random.randint(0, HEIGHT - 1)

    def draw(self):
        for y in range(HEIGHT):
            for x in range(WIDTH):
                if x == self.x and y == self.y:
                    print(FOOD_SYMBOL, end='')
                else:
                    print(' ', end='')
            print()

# 游戏初始化
snake = Snake()
food = Food()

# 游戏主循环
running = True
while running:
    # 绘制游戏界面
    snake.draw()
    food.draw()

    # 接收玩家输入
    if msvcrt.kbhit():
        key = msvcrt.getch().decode()
        if key == 'w' or key == 'W':
            snake.change_direction('up')
        elif key == 's' or key == 'S':
            snake.change_direction('down')
        elif key == 'a' or key == 'A':
            snake.change_direction('left')
        elif key == 'd' or key == 'D':
            snake.change_direction('right')

    # 蛇移动
    snake.move()

    # 判断是否吃到食物
    if snake.body[0] == (food.x, food.y):
        snake.body.append((food.x, food.y))
        food = Food()

    # 判断游戏结束条件
    if snake.check_collision():
        running = False

    print()

# 游戏结束提示
print('游戏结束！')

这是一个简单的文本版贪吃蛇游戏，您可以在此基础上进行更多的自定义和改进。希望您玩得开心！
