第一个Python窗口

import tkinter

def my_window(w, h):

 ws = root1.winfo_screenwidth();

 hs = root1.winfo_screenheight();

 x = (ws/2) - (w/2);

 y = (hs/2) - (h/2);

 root1.geometry('%dx%d+%d+%d'%(w, h, x, y));

root1 = tkinter.Tk(className='python windows app')

my_window(640, 480);

root1.mainloop();

无废话，撸起袖子就是，干！
