python画一个简单的五角星或者多边形

• 首先，我们需要确定五个角的坐标，
  
  #绘制多边形
  from tkinter import *
  import math as m
  
  root = Tk()
  w = Canvas(root,width=200,height=150,background="red")
  w.pack()
  center_x = 100
  center_y = 70
  r=50
  points =[
      #左上点
      center_x - int(r * m.sin(2 * m.pi / 5)),
      center_y - int(r * m.cos(2 * m.pi / 5)),
      # 右上点
      center_x + int(r * m.sin(2 * m.pi / 5)),
      center_y - int(r * m.cos(2 * m.pi / 5)),
      # 左下点
      # center_x - int(r * m.sin(m.pi / 5)),
      # center_y + int(r * m.cos(m.pi / 5)),
      center_x - int(r * m.sin(m.pi / 5)),
      center_y + int(r * m.cos(m.pi / 5)),
      # 顶点
      center_x,
      center_y - r,
      #右下点
      center_x + int(r * m.sin(m.pi / 5)),
      center_y + int(r * m.cos(m.pi / 5)),
  ]
  w.create_polygon(points,outline="green",fill="yellow")
  mainloop()
