Python2 练习实例58
Python 100例题目: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

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:
