各位大神好！

初学PYTHON，遇到的第一个问题就是

NameError: name 'TK' is not defined 请问该如何解决？

attchgui.py 的代码内容如下(python3.4)：

# -*- coding: utf-8 -*-
from tkinter import *
import os
from tkinter102 import MyGui
mainwin = TK()
Label(mainwin,text = __name__).pack()
popup = Toplevel()
Label(popup, text = 'Attach').pack(side = LEFT)
MyGui(popup).pack(side = RIGHT)
mainwin.mainloop()

-- 运行报错
NameError: name 'TK' is not defined 请问该如何解决？

from tkinter import * 改成Tkinter

'TK'应为'Tk'.
