tkinter：滑杆调整，绘制正多边形

前言

本篇我们制作一个项目，左下方有一个tkinter滑杆，可以调整正多边形的边数。

效果展示

 

代码

import tkinter as tk
import math
root = tk.Tk()
w = tk.Canvas(root, width = 1200, height = 670,highlightthickness=0)
w.pack()
x = 600
y = 300
r = 290
n=3
points = []
for i in range(n): 
    points.append(x - r * math.sin(2 * math.pi * i / n))
    points.append(y - r * math.cos(2 * math.pi * i / n))
c=w.create_polygon(points, outline = "green", fill = "yellow")
def flush(get):
    global c
    n=int(get)
    w.delete(c)
    points = []
    for i in range(n): 
        points.append(x - r * math.sin(2 * math.pi * i / n))
        points.append(y - r * math.cos(2 * math.pi * i / n))
    c=w.create_polygon(points, outline = "green", fill = "yellow")
s = tk.Scale(w,orient='horizontal',from_=3,to=33,command=flush,length=600,tickinterval=5,foreground='blue').place(x=15,y=600)
root.mainloop()
