Python使用turtle库绘制“李”

A：

import turtle

# 创建画笔
pen = turtle.Pen()

# 设置画笔初始位置
pen.setposition(-100, 0)

# 绘制“李”
pen.pendown()
pen.forward(100)
pen.right(90)
pen.forward(100)
pen.left(90)
pen.forward(50)
pen.left(90)
pen.forward(50)
pen.right(180)
pen.forward(100)
pen.penup()
pen.setposition(-50, 0)
pen.pendown()
pen.forward(50)

# 隐藏画笔
pen.hideturtle()

# 等待关闭窗口
turtle.done()

执行上述代码，就可以看到 turtle 绘制出了一个“李”字。
