python计算机图形学画简笔画 大白

要用Python画出大白的简笔画，可以借助Python中的turtle库，它专门用于绘制图形和动画。

下面是一个用turtle库绘制大白的简笔画的示例代码：

import turtle

# 设置画笔颜色和大小
turtle.color('white', 'white')
turtle.pensize(5)

# 绘制大白的头部
turtle.begin_fill()
turtle.circle(100)
turtle.end_fill()

# 绘制大白的眼睛
turtle.penup()
turtle.goto(-40, 120)
turtle.pendown()
turtle.color('black', 'black')
turtle.begin_fill()
turtle.circle(20)
turtle.end_fill()

turtle.penup()
turtle.goto(40, 120)
turtle.pendown()
turtle.begin_fill()
turtle.circle(20)
turtle.end_fill()

# 绘制大白的嘴巴
turtle.penup()
turtle.goto(-60, 60)
turtle.pendown()
turtle.color('red', 'red')
turtle.begin_fill()
turtle.right(90)
turtle.circle(60, 180)
turtle.end_fill()

# 绘制大白的身体
turtle.penup()
turtle.goto(-150, -50)
turtle.pendown()
turtle.color('white', 'white')
turtle.begin_fill()
turtle.right(90)
turtle.forward(200)
turtle.right(90)
turtle.forward(300)
turtle.right(90)
turtle.forward(200)
turtle.right(90)
turtle.forward(300)
turtle.end_fill()

# 绘制大白的手臂
turtle.penup()
turtle.goto(-150, -50)
turtle.pendown()
turtle.color('black', 'white')
turtle.begin_fill()
turtle.right(45)
turtle.forward(100)
turtle.right(90)
turtle.forward(100)
turtle.right(45)
turtle.end_fill()

turtle.penup()
turtle.goto(150, -50)
turtle.pendown()
turtle.color('black', 'white')
turtle.begin_fill()
turtle.left(45)
turtle.forward(100)
turtle.left(90)
turtle.forward(100)
turtle.left(45)
turtle.end_fill()

# 绘制大白的脚
turtle.penup()
turtle.goto(-100, -250)
turtle.pendown()
turtle.color('black', 'white')
turtle.begin_fill()
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(50)
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(50)
turtle.end_fill()

turtle.penup()
turtle.goto(100, -250)
turtle.pendown()
turtle.color('black', 'white')
turtle.begin_fill()
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(50)
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(50)
turtle.end_fill()

# 隐藏画笔
turtle.hideturtle()

# 显示绘制结果
turtle.done()

运行上述代码，即可在窗口中看到一个用turtle库绘制的大白的简笔画。
