tkinter是内置的模块，不同的版本的导入形式不同，现总结如下

#coding=utf-8

import os, sys
try:
    from tkinter import *
except ImportError:  #Python 2.x
    PythonVersion = 2
    from Tkinter import *
    from tkFont import Font
    from ttk import *
    from tkMessageBox import *
    import tkFileDialog
else:  #Python 3.x
    PythonVersion = 3
    from tkinter.font import Font
    from tkinter.ttk import *
    from tkinter.messagebox import *
