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 - #!/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()
以上实例输出结果为：
