使用Tkinter实现python图形界面Hello World

第一个窗口吧，很简单Hello.py：

from Tkinter import*
from tkMessageBox import*

root = Tk() 

root.mainloop() 

如图：

放个按钮，注册个事件BtnClick.py

from Tkinter import * 
from tkMessageBox import * 

def button_click(): 
    showinfo('first application','Hello world!') 

root = Tk() 
b = Button(root,text = 'OK',command = button_click) 
b.pack(side = TOP) 

root.mainloop() 

 如图
