题目:画图,学用rectangle画方形。   

程序分析:

rectangle(int left, int top, int right, int bottom)

参数说明:(left ,top )为矩形的左上坐标,(right,bottom)为矩形的右下坐标,两者可确定一个矩形的大小

实例(Python 2.0+)

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
if __name__ == '__main__':
 from Tkinter import *
 root = Tk()
 root.title('Canvas')
 canvas = Canvas(root,width = 400,height = 400,bg = 'yellow')
 x0 = 263
 y0 = 263
 y1 = 275
 x1 = 275
 for i in range(19):
 canvas.create_rectangle(x0,y0,x1,y1)
 x0 -= 5
 y0 -= 5
 x1 += 5
 y1 += 5
 
 canvas.pack()
 root.mainloop()
