用python画一个小乌龟

好的，以下是使用Python turtle库绘制一个小乌龟的代码：

import turtle

# 设置画布大小
turtle.setup(600, 600)

# 创建画笔
pen = turtle.Turtle()

# 设置画笔颜色和粗细
pen.color('green')
pen.pensize(5)

# 绘制龟头
pen.fillcolor('green')
pen.begin_fill()
pen.right(45)
pen.forward(80)
pen.right(135)
pen.forward(80)
pen.right(135)
pen.forward(80)
pen.right(135)
pen.forward(80)
pen.end_fill()

# 绘制龟身
pen.fillcolor('yellow')
pen.begin_fill()
pen.right(45)
pen.forward(120)
pen.right(90)
pen.forward(120)
pen.right(90)
pen.forward(120)
pen.right(90)
pen.forward(120)
pen.end_fill()

# 绘制龟脚
pen.penup()
pen.goto(-60, -120)
pen.pendown()
pen.fillcolor('green')
pen.begin_fill()
pen.right(45)
pen.forward(60)
pen.right(90)
pen.forward(60)
pen.right(90)
pen.forward(60)
pen.right(90)
pen.forward(60)
pen.end_fill()

pen.penup()
pen.goto(0, -120)
pen.pendown()
pen.fillcolor('green')
pen.begin_fill()
pen.right(45)
pen.forward(60)
pen.right(90)
pen.forward(60)
pen.right(90)
pen.forward(60)
pen.right(90)
pen.forward(60)
pen.end_fill()

# 隐藏画笔
pen.hideturtle()

# 显示绘画窗口
turtle.done()

运行以上代码后，你就可以看到一个用绿色和黄色绘制的小乌龟啦！
