Python 100例题目：利用ellipse 和 rectangle 画图。。
程序分析：无。
程序源代码：
#!/usr/bin/python# -*- coding: UTF-8 -*-if __name__ == '__main__': from Tkinter import * canvas = Canvas(width = 400,height = 600,bg = 'white') left = 20 right = 50 top = 50 num = 15 for i in range(num): canvas.create_oval(250 - right,250 - left,250 + right,250 + left) canvas.create_oval(250 - 20,250 - top,250 + 20,250 + top) canvas.create_rectangle(20 - 2 * i,20 - 2 * i,10 * (i + 2),10 * ( i + 2)) right += 5 left += 5 top += 10 canvas.pack() mainloop()
以上实例输出结果为：
