给我turtle吃豆人的程序

当然可以，以下是Python代码：

import turtle

# 设置画布
turtle.setup(400,400)

# 定义方向
directions = [(0, 20), (0, -20), (-20, 0), (20, 0)]

# 定义函数，绘制豆子
def draw_bean(x, y):
    turtle.up()
    turtle.goto(x, y)
    turtle.down()
    turtle.begin_fill()
    turtle.circle(10)
    turtle.end_fill()

# 定义函数，绘制墙
def draw_wall(x, y):
    turtle.up()
    turtle.goto(x, y)
    turtle.down()
    turtle.setheading(0)
    turtle.forward(40)
    turtle.left(90)
    turtle.forward(40)
    turtle.left(90)
    turtle.forward(40)
    turtle.left(90)
    turtle.forward(40)

# 定义函数，移动小乌龟并判断碰撞
def move_turtle():
    turtle.onkey(None,'Up')
    turtle.onkey(None,'Left')
    turtle.onkey(None,'Down')
    turtle.onkey(None,'Right')
    turtle.clear()
    turtle.setheading(turtle.direction)
    turtle.forward(20)

    x, y = turtle.position()

    # 判断是否碰墙
    hit_wall = False
    if x < -180 or x > 160 or y < -180 or y > 160:
        hit_wall = True
        turtle.write('Game Over!', font=('Arial', 30, 'normal'))

    # 判断是否碰豆子
    for bean in beans:
        if bean.isvisible() and turtle.distance(bean) < 20:
            bean.ht()
            beans.remove(bean)

    # 判断是否吃完豆子
    if len(beans) == 0:
        turtle.write('You Win!', font=('Arial', 30, 'normal'))

    turtle.onkey(lambda: change_direction(0), 'Up')
    turtle.onkey(lambda: change_direction(1), 'Left')
    turtle.onkey(lambda: change_direction(2), 'Down')
    turtle.onkey(lambda: change_direction(3), 'Right')

    if hit_wall == False:
        turtle.ontimer(move_turtle, 200)

# 定义函数，改变方向
def change_direction(idx):
    turtle.direction = directions[idx]

# 绘制地图
map_grid = [
    "+++++++++++++++",
    "+o+o+o+o+o+o+o+o+",
    "+o+o+o+++++o+o+o+",
    "+o+o+o+o+o+o+o+o+",
    "+o+o+++o++o+++o+o+",
    "+o+o+o+o++o+o+o+o+",
    "+o++++++oo+o+++++",
    "+o+o+o+++o+o+o+o+",
    "+o+o+o+o+o+o+o+o+",
    "+o+o+o++o++o+o+o+",
    "+o+o+o+o+o+o+o+o+",
    "+o+o++++o++++o+o+",
    "+o+o+o+o+o+o+o+o+",
    "+o+o+o+o+o+o+o+o+",
    "+++++++++++++++"
]

# 绘制地图中的豆子和墙
beans = []
for i in range(len(map_grid)):
    for j in range(len(map_grid[i])):
        if map_grid[i][j] == 'o':
            beans.append(turtle.Turtle(visible=False))
            beans[-1].penup()
            beans[-1].goto(j * 20 - 180, 180 - i * 20)
            beans[-1].pendown()
            beans[-1].begin_fill()
            beans[-1].circle(10)
            beans[-1].end_fill()
        elif map_grid[i][j] == '+':
            draw_wall(j * 20 - 200, 200 - i * 20)

# 准备小乌龟
turtle.shape('turtle')
turtle.color('blue')
turtle.penup()
turtle.goto(0, 0)
turtle.pendown()
turtle.direction = directions[3]

# 设置键盘事件
turtle.onkey(lambda: change_direction(0), 'Up')
turtle.onkey(lambda: change_direction(1), 'Left')
turtle.onkey(lambda: change_direction(2), 'Down')
turtle.onkey(lambda: change_direction(3), 'Right')

# 启动循环
turtle.listen()
move_turtle()
turtle.done()

该程序实现了吃豆人游戏，地图和方格大小可调整。玩家通过方向键控制小乌龟移动吃掉豆子，碰到墙壁会游戏结束。
