贪吃蛇 python代码

### 回答1：
贪吃蛇是一个经典的游戏，可以用 Python 编写代码实现。这里是一个简单的贪吃蛇游戏的 Python 代码示例：

import turtle
import time

# 设置画布大小
turtle.setup(width=600, height=600)

# 创建一个 Turtle 实例
snake = turtle.Turtle()
snake.speed(10)
snake.penup()

# 设置食物的位置
food = turtle.Turtle()
food.speed(0)
food.color("red")
food.penup()
food.goto(0, 100)
food.pendown()
food.begin_fill()
food.circle(10)
food.end_fill()

# 定义蛇的移动方向
directions = ["down", "right", "up", "left"]

# 开始游戏
while True:
    snake.forward(20)

    # 判断是否吃到食物
    if snake.distance(food) < 20:
        food.goto(0, 0)

    time.sleep(0.2)

turtle.done()

希望这个代码示例对你有所帮助。

贪吃蛇是一种经典的游戏，在Python中可以通过编写一些简单的代码来实现。下面是一个基本的贪吃蛇代码示例：

import turtle
import time
import random

delay = 0.1

score = 0
high_score = 0

# 创建窗口
window = turtle.Screen()
window.title("贪吃蛇游戏")
window.bgcolor("black")
window.setup(width=600, height=600)
window.tracer(0)

# 创建蛇头
head = turtle.Turtle()
head.speed(0)
head.shape("square")
head.color("white")
head.penup()
head.goto(0, 0)
head.direction = "Stop"

# 创建食物
food = turtle.Turtle()
food.speed(0)
food.shape("circle")
food.color("red")
food.penup()
food.goto(0, 100)

segments = []

# 计分板
pen = turtle.Turtle()
pen.speed(0)
pen.shape("square")
pen.color("white")
pen.penup()
pen.hideturtle()
pen.goto(0, 260)
pen.write("得分: 0  最高分: 0", align="center", font=("Courier", 24, "normal"))

# 控制蛇的方向
def go_up():
    if head.direction != "down":
        head.direction = "up"

def go_down():
    if head.direction != "up":
        head.direction = "down"

def go_left():
    if head.direction != "right":
        head.direction = "left"

def go_right():
    if head.direction != "left":
        head.direction = "right"

def move():
    if head.direction == "up":
        y = head.ycor()
        head.sety(y + 20)

    if head.direction == "down":
        y = head.ycor()
        head.sety(y - 20)

    if head.direction == "left":
        x = head.xcor()
        head.setx(x - 20)

    if head.direction == "right":
        x = head.xcor()
        head.setx(x + 20)

# 键盘绑定
window.listen()
window.onkey(go_up, "w")
window.onkey(go_down, "s")
window.onkey(go_left, "a")
window.onkey(go_right, "d")

# 游戏主循环
while True:
    window.update()

    # 判断蛇头是否和食物碰到
    if head.distance(food) < 20:
        # 更新食物的位置
        x = random.randint(-280, 280)
        y = random.randint(-280, 280)
        food.goto(x, y)

        # 添加一个身体段
        new_segment = turtle.Turtle()
        new_segment.speed(0)
        new_segment.shape("square")
        new_segment.color("grey")
        new_segment.penup()
        segments.append(new_segment)

        # 增加得分
        score += 10

        if score > high_score:
            high_score = score

        pen.clear()
        pen.write("得分: {}  最高分: {}".format(score, high_score), align="center", font=("Courier", 24, "normal"))

    # 更新身体段的位置
    for index in range(len(segments) - 1, 0, -1):
        x = segments[index - 1].xcor()
        y = segments[index - 1].ycor()
        segments[index].goto(x, y)

    # 更新蛇头的位置
    if len(segments) > 0:
        x = head.xcor()
        y = head.ycor()
        segments[0].goto(x, y)

    move()

    # 判断蛇头是否和身体碰撞
    for segment in segments:
        if segment.distance(head) < 20:
            time.sleep(1)
            head.goto(0, 0)
            head.direction = "Stop"

            for segment in segments:
                segment.goto(1000, 1000)

            segments.clear()

            score = 0
            pen.clear()
            pen.write("得分: {}  最高分: {}".format(score, high_score), align="center", font=("Courier", 24, "normal"))

    time.sleep(delay)

window.mainloop()

这段代码使用了Turtle库来创建游戏窗口和游戏中的蛇、食物等元素。通过键盘监听来获取玩家的输入，控制蛇的移动方向。蛇的每一步移动都会检测是否碰到食物或者身体，根据不同情况来更新游戏状态。同时，还有一个计分板记录游戏得分和最高分数。游戏主循环不断重复，以实现动态的游戏画面。
