python导入tkinter后运行代码提示tk未定义

# -*- encoding：utf-8 -*-
from tkinter  import *
import tkinter.simpledialog as dl
import tkinter.messagebox as mb
win=TK()
w=tkinter.Label(win,text="Guess Number Game")
w.pack()
mb.showinfo("welcome to guess number game")

number=88
while True:
        guess=dl.askinteger("Number","what's your number")
        if guess==number:
                output="bingo! you are right,but you do not win any prize!"
                mb.showinfo("result",output)
        elif guess<number:
                output="no ,the number is a lower than that"
                mb.showinfo("result",output)
        else :
                output="no,the number is a higher than that"
                mb.showinfo("result",output)
print("done!")

运行上述代码，提示
Traceback (most recent call last):
  File "tk1.py", line 5, in <module>
    win=TK()
NameError: name 'TK' is not defined

安装python3.6版本，，上面问题  该怎么解决？初学python有很多不懂的地方，希望大家能够不吝赐教，谢谢!
