python代码：画图哆啦a梦（不上颜色）

下面是一个简单的 Python 代码示例，可以绘制一个哆啦A梦的轮廓：

import turtle

# 设置画布大小
turtle.setup(800, 600)

# 绘制圆形
turtle.penup()
turtle.goto(0, -200)
turtle.pendown()
turtle.circle(200)

# 绘制脸部
turtle.penup()
turtle.goto(0, 0)
turtle.pendown()
turtle.circle(150)

# 绘制鼻子
turtle.penup()
turtle.goto(0, 50)
turtle.pendown()
turtle.begin_fill()
turtle.circle(30)
turtle.end_fill()

# 绘制眼睛
turtle.penup()
turtle.goto(-70, 110)
turtle.pendown()
turtle.begin_fill()
turtle.circle(30)
turtle.end_fill()
turtle.penup()
turtle.goto(-70, 130)
turtle.pendown()
turtle.circle(10)
turtle.penup()
turtle.goto(70, 110)
turtle.pendown()
turtle.begin_fill()
turtle.circle(30)
turtle.end_fill()
turtle.penup()
turtle.goto(70, 130)
turtle.pendown()
turtle.circle(10)

# 绘制嘴巴
turtle.penup()
turtle.goto(-50, -20)
turtle.pendown()
turtle.circle(50, -180)

# 绘制胡须
turtle.penup()
turtle.goto(-80, 40)
turtle.pendown()
turtle.setheading(-60)
turtle.circle(80, 120)
turtle.penup()
turtle.goto(-80, 20)
turtle.pendown()
turtle.setheading(-60)
turtle.circle(80, 120)
turtle.penup()
turtle.goto(-80, 0)
turtle.pendown()
turtle.setheading(-60)
turtle.circle(80, 120)
turtle.penup()
turtle.goto(80, 40)
turtle.pendown()
turtle.setheading(60)
turtle.circle(-80, 120)
turtle.penup()
turtle.goto(80, 20)
turtle.pendown()
turtle.setheading(60)
turtle.circle(-80, 120)
turtle.penup()
turtle.goto(80, 0)
turtle.pendown()
turtle.setheading(60)
turtle.circle(-80, 120)

# 隐藏画笔
turtle.hideturtle()

# 显示绘图窗口
turtle.done()

这个代码使用了 Python 内置的 `turtle` 库来绘制图形。如果你想要更好地掌握这个库，可以查看该库的官方文档或者相关的教程。
