帮我写一个贪吃蛇的代码

好的，这是一份用 Python 实现的简单的贪吃蛇游戏代码：

import turtle
import time

# 设置窗口大小
turtle.setup(width=600, height=600)

# 创建一个 Turtle 对象
snake = turtle.Turtle()

# 设置速度
snake.speed(10)

# 设置蛇头的形状
snake.shape("square")

# 向上移动
snake.up()

# 设置起始位置
snake.goto(0, 0)

# 设置方向向右
snake.right(90)

# 开始移动
while True:
    snake.forward(10)
    time.sleep(0.2)

这份代码只是一个简单的演示，仅能实现蛇头向右移动，你可以根据需要添加更多的功能。

用java帮我写一个贪吃蛇代码

好的，我可以回答这个问题。以下是一个简单的贪吃蛇代码示例，使用Java编写：

能使用st语言帮我写一个贪吃蛇代码吗》
