python的turtle绘制喜羊羊

Python的turtle库是一种基于Python语言的图形化绘图工具，可以用它来绘制各种形状的图案，包括喜羊羊。要绘制喜羊羊，可以按照以下步骤进行：

1. 导入turtle库

import turtle

2. 定义一个画笔

pen = turtle.Turtle()

3. 绘制喜羊羊的头部

pen.pensize(4)
pen.color('black', 'white')
pen.begin_fill()
pen.circle(100)
pen.end_fill()

4. 绘制喜羊羊的眼睛

pen.penup()
pen.goto(-40, 120)
pen.pendown()
pen.color('black', 'black')
pen.begin_fill()
pen.circle(20)
pen.end_fill()

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

pen.penup()
pen.goto(-30, 130)
pen.pendown()
pen.color('white', 'white')
pen.begin_fill()
pen.circle(10)
pen.end_fill()

pen.penup()
pen.goto(50, 130)
pen.pendown()
pen.begin_fill()
pen.circle(10)
pen.end_fill()

5. 绘制喜羊羊的鼻子

pen.penup()
pen.goto(0, 90)
pen.pendown()
pen.color('black', 'red')
pen.begin_fill()
pen.circle(30)
pen.end_fill()

pen.penup()
pen.goto(-10, 80)
pen.pendown()
pen.color('white', 'white')
pen.begin_fill()
pen.circle(10)
pen.end_fill()

6. 绘制喜羊羊的嘴巴

pen.penup()
pen.goto(-30, 60)
pen.pendown()
pen.color('black', 'white')
pen.begin_fill()
for i in range(120):
    pen.forward(1)
    pen.right(3)
for i in range(60):
    pen.forward(1)
    pen.right(1.5)
for i in range(120):
    pen.forward(1)
    pen.right(3)
for i in range(60):
    pen.forward(1)
    pen.right(1.5)
pen.end_fill()

7. 绘制喜羊羊的身体和四肢

# 身体
pen.penup()
pen.goto(-150, -100)
pen.pendown()
pen.color('black', 'white')
pen.begin_fill()
for i in range(2):
    pen.forward(300)
    pen.left(90)
    pen.forward(200)
    pen.left(90)
pen.end_fill()

# 四肢
for i in range(2):
    pen.penup()
    pen.goto(-150 + i * 300, -100)
    pen.pendown()
    pen.color('black', 'white')
    pen.begin_fill()
    pen.circle(50, 180)
    pen.forward(100)
    pen.circle(-50, 180)
    pen.end_fill()

# 脚
for i in range(2):
    pen.penup()
    pen.goto(-150 + i * 300, -200)
    pen.pendown()
    pen.color('black', 'white')
    pen.begin_fill()
    pen.circle(30)
    pen.end_fill()

# 尾巴
pen.penup()
pen.goto(-100, -200)
pen.pendown()
pen.color('black', 'white')
pen.begin_fill()
for i in range(4):
    pen.forward(50)
    pen.right(90)
    pen.forward(50)
    pen.left(90)
for i in range(2):
    pen.forward(50)
    pen.right(90)
    pen.forward(100)
    pen.right(90)
for i in range(2):
    pen.forward(50)
    pen.left(90)
    pen.forward(100)
    pen.left(90)

# 头顶毛发
for i in range(2):
    pen.penup()
    if i == 0:
        x, y = -20, 180
        angle = 45
        length = 70
        width = 15
        color = 'orange'
    else:
        x, y = 20, 180
        angle = -45
        length = -70
        width = -15
        color = 'yellow'
    pen.goto(x, y)
    pen.setheading(angle)
    pen.pendown()
    pen.pensize(abs(width))
    pen.color(color, color)
    for j in range(abs(width)):
        pen.forward(abs(length))
        if width > 0:
            length -= 2
        else:
            length += 2
        pen.right(angle / abs(angle) * (90 / abs(width)))

8. 最后，隐藏画笔并展示绘制结果

pen.hideturtle()

turtle.done()
