请使用Python画一只乌龟

好的，我可以回答这个问题。以下是使用Python绘制乌龟的代码：

import turtle

# 创建一个画布和画笔
canvas = turtle.Screen()
pen = turtle.Turtle()

# 绘制乌龟
pen.color('green')
pen.pensize(5)
pen.speed(1)

# 绘制乌龟的头
pen.penup()
pen.goto(0, 100)
pen.pendown()
pen.circle(50)

# 绘制乌龟的身体
pen.penup()
pen.goto(0, 50)
pen.pendown()
pen.circle(100)

# 绘制乌龟的四肢
pen.penup()
pen.goto(-50, 0)
pen.pendown()
pen.forward(100)

pen.penup()
pen.goto(50, 0)
pen.pendown()
pen.forward(100)

pen.penup()
pen.goto(-70, -50)
pen.pendown()
pen.forward(40)

pen.penup()
pen.goto(30, -50)
pen.pendown()
pen.forward(40)

# 隐藏画笔
pen.hideturtle()

# 关闭画布
canvas.exitonclick()

希望这个代码对你有所帮助！
