用Python-Turtle做贪吃蛇

t.onkey(start_game, 'space')
t.listen()
t.mainloop()

事实上，这只是一个比较简陋的模型……
但是，我一定会努力的！！！

看起来您发了一个未完成的贪吃蛇游戏的源码片段。但代码有点不完整，后面的部分似乎没有粘贴完。下面给您一份完整的示例，您可以参考这个完整的游戏代码：

import random
import turtle as t

t.bgcolor('yellow')
# Caterpillar setup
caterpillar = t.Turtle()
caterpillar.shape('square')
caterpillar.color('red')
caterpillar.speed(0)
caterpillar.penup()
caterpillar.hideturtle()

# Leaf setup
leaf = t.Turtle()
leaf_shape = ((0, 0), (14, 2), (18, 6), (20, 20), (6, 18), (2, 14))
t.register_shape('leaf', leaf_shape)
leaf.shape('leaf')
leaf.color('green')
leaf.penup()
leaf.hideturtle()
leaf.speed(0)

game_started = False
text_turtle = t.Turtle()
text_turtle.write('Press SPACE to start', align='center', font=('Arial', 16, 'bold'))
text_turtle.hideturtle()

score_turtle = t.Turtle()
score_turtle.hideturtle()
score_turtle.speed(0)

# Check if the caterpillar is outside the window
def outside_window(caterpillar):
    left_wall = -t.window_width() / 2
    right_wall = t.window_width() / 2
    top_wall = t.window_height() / 2
    bottom_wall = -t.window_height() / 2
    (x, y) = caterpillar.pos()
    outside = x < left_wall or x > right_wall or y < bottom_wall or y > top_wall
    return outside

# Display game over message
def game_over():
    caterpillar.color('yellow')
    leaf.color('yellow')
    t.penup()
    t.hideturtle()
    t.write('GAME OVER!', align='center', font=('Arial', 30, 'normal'))

# Display the current score
def display_score(current_score):
    score_turtle.clear()
    score_turtle.penup()

    y = (t.window_height() / 2) - 50
    score_turtle.setpos(x, y)

# Place the leaf at a random location
def place_leaf():
    leaf.ht()
    leaf.setx(random.randint(-200, 200))
    leaf.sety(random.randint(-200, 200))
    leaf.st()

# Start the game

    global game_started
    if game_started:
        return
    game_started = True

    score = 0
    text_turtle.clear()

    caterpillar_speed = 2
    caterpillar_length = 3
    caterpillar.shapesize(1, caterpillar_length, 1)
    caterpillar.showturtle()
    display_score(score)
    place_leaf()

    while True:
        caterpillar.forward(caterpillar_speed)
        if caterpillar.distance(leaf) < 20:
            place_leaf()
            caterpillar_length = caterpillar_length + 1
            caterpillar.shapesize(1, caterpillar_length, 1)
            caterpillar_speed = caterpillar_speed + 1
            score = score + 10
            display_score(score)
        if outside_window(caterpillar):
            game_over()
            break

# Turn the caterpillar upwards
def move_up():
    if caterpillar.heading() != 270:
        caterpillar.setheading(90)

# Turn the caterpillar downwards
def move_down():
    if caterpillar.heading() != 90:
        caterpillar.setheading(270)

# Turn the caterpillar left
def move_left():
    if caterpillar.heading() != 0:
        caterpillar.setheading(180)

# Turn the caterpillar right
def move_right():
    if caterpillar.heading() != 180:
        caterpillar.setheading(0)

# Bind keyboard inputs to functions
t.onkey(start_game, 'space')
t.onkey(move_up, 'Up')
t.onkey(move_down, 'Down')
t.onkey(move_left, 'Left')
t.onkey(move_right, 'Right')
t.listen()
t.mainloop()

这个代码展示了如何用Python的Turtle库制作一个简单的贪吃蛇游戏。按下空格键（SPACE）开始游戏，并用方向键（上、下、左、右）控制贪吃蛇的移动方向。游戏过程中得吃绿叶来增长长度并增加分数。如果贪吃蛇撞到窗口边界，游戏结束，显示"GAME OVER"。
