IDLE线条小狗代码

### 使用 Python IDLE 绘制小狗图案

为了实现这一目标，可以利用 `turtle` 库来完成图形绘制的任务。下面是一个完整的代码示例，用于在 Python IDLE 中创建并显示一个小狗图案。

import turtle

def draw_dog():
    screen = turtle.Screen()
    screen.bgcolor("white")

    dog = turtle.Turtle()
    dog.speed(5)

    # 头部
    dog.penup()
    dog.goto(-70, 90)
    dog.pendown()
    dog.begin_fill()
    dog.circle(30)
    dog.end_fill()

    # 耳朵
    dog.penup()
    dog.goto(-120, 80)
    dog.pendown()
    dog.setheading(-45)
    dog.begin_fill()
    dog.circle(20, 180)
    dog.left(90)
    dog.forward(40)
    dog.end_fill()

    # 眼睛
    dog.penup()
    dog.goto(-60, 110)
    dog.fillcolor('black')
    dog.begin_fill()
    dog.circle(3)
    dog.end_fill()

    dog.penup()
    dog.goto(-80, 110)
    dog.begin_fill()
    dog.circle(3)
    dog.end_fill()

    # 鼻子
    dog.penup()
    dog.goto(-70, 90)
    dog.pendown()
    dog.dot(10,'black')

    # 嘴巴
    dog.penup()
    dog.goto(-60, 80)
    dog.pendown()
    dog.right(90)
    dog.circle(10,-180)

    # 身体
    dog.penup()
    dog.goto(-50, 50)
    dog.pendown()
    dog.begin_fill()
    dog.forward(40)
    dog.left(90)
    dog.forward(60)
    dog.left(90)
    dog.forward(40)
    dog.left(90)
    dog.forward(60)
    dog.end_fill()

    # 尾巴
    dog.penup()
    dog.goto(10, 50)
    dog.pendown()
    dog.color('brown')
    dog.begin_fill()
    dog.circle(10, 180)
    dog.end_fill()

    # 四肢
    dog.penup()
    dog.goto(-40, 50)
    dog.pensize(5)
    dog.pendown()
    dog.goto(-40, 10)

    dog.penup()
    dog.goto(-20, 50)
    dog.pendown()
    dog.goto(-20, 10)

    dog.penup()
    dog.goto(-40, -10)
    dog.pendown()
    dog.goto(-40, -50)

    dog.penup()
    dog.goto(-20, -10)
    dog.pendown()
    dog.goto(-20, -50)

    dog.hideturtle()
    turtle.done()

draw_dog()

这段代码通过调用 `turtle` 的各种方法实现了小狗身体各部分的构建[^4]。需要注意的是，在实际环境中执行此脚本前，请确认已安装了最新版本的 Python 和其自带的标准库 `turtle`[^2]。
