python画五角星外接正五边形

好的，以下是Python代码实现五角星外接正五边形的过程：

import turtle
# 设置画笔
pen = turtle.Turtle()
pen.speed(10)
pen.color('red')

# 画五角星
def draw_star(size):
    for i in range(5):
        pen.forward(size)
        pen.right(144)
        pen.forward(size)
        pen.left(72)

# 画正五边形
def draw_pentagon(size):
    for i in range(5):
        pen.forward(size)
        pen.right(72)

# 计算正五边形的边长
def calc_size(radius):
    return radius * 2 * (3 ** 0.5) / 5

# 设置起始位置
pen.penup()
pen.goto(-100, 0)
pen.pendown()

# 画五角星外接正五边形
radius = 100
size = calc_size(radius)
draw_star(size)
draw_pentagon(size)

turtle.done()
