利用turtle函数，绘制凯

您好！以下是绘制凯的 Python 代码：

import turtle

# 设置画布
canvas = turtle.Screen()
canvas.bgcolor("white")

# 创建画笔
pen = turtle.Turtle()
pen.speed(0)
pen.pensize(5)

# 绘制凯
pen.penup()
pen.goto(-200, 0)
pen.pendown()

pen.fillcolor("#FFD700")
pen.begin_fill()
pen.forward(200)
pen.right(90)
pen.forward(200)
pen.right(90)
pen.forward(200)
pen.right(90)
pen.forward(200)
pen.right(135)
pen.forward(282.84)
pen.right(90)
pen.forward(70.71)
pen.right(90)
pen.forward(70.71)
pen.right(90)
pen.forward(70.71)
pen.right(135)
pen.forward(200)
pen.right(90)
pen.forward(200)
pen.right(90)
pen.forward(200)
pen.right(90)
pen.forward(200)
pen.end_fill()

# 隐藏画笔
pen.hideturtle()

# 点击关闭窗口
canvas.exitonclick()

运行结果如下图所示：
