我用this link作为灵感。我的问题是如何将这段代码重写成一个类。我是一个非常新的课程，我试图了解我需要使用的地方（自我）以及我没有通过一个例子。
root = Tkinter.Tk()
timeFrame = LabelFrame(root, text='Time Frame', width=1200)
timeFrame.grid(row=2,column=2, sticky=W)
timer = [0,0,0] # [minutes ,seconds, centiseconds]
def update_time():
if (state):
global timer
timer[2] += 1
if (timer[2] >= 100): #100 centiseconds --> 1 second
timer[2] = 0
timer[1] += 1 #add 1 second
if (timer[1] >= 60): #60 seconds --> 1 minute
timer[0] += 1
timer[1] = 0
timeString = str(timer[0]) + ':' + str(timer[1]) + ':' + str(timer[2])
show.config(text=timeString)
root.after(10, update_time)
def start():

print 'Clock Running...'
def pause():
global state

timeString = str(timer[0]) + ':' + str(timer[1]) + ':' + str(timer[2])
timeList.insert(END, timeString)

print 'Clock is Reset'
show.config(text='00:00:00')
state = False
resetButton = Button(timeFrame, text='Reset', command=resetTime)
resetButton.grid(row=2,column=1)
pauseButton = Button(timeFrame, text='Pause', command=pause)
pauseButton.grid(row=1,column=1)

# Quit Button

update_time()
root.mainloop()
上面的代码适用于＆＃34;小心跳＆＃34;在python 3.5.0上 谁能帮助我理解如何将这段代码翻译成一个类？
这是我做我想做的最好的尝试：

有多种方法可以做到这一点。我会告诉你我的预备版本
from tkinter import * #if below 3.X it's Tkinter
class Anynameyoulike(Tk): #passing Tk to the class directly, makes most sense for me
def __init__(self): #__init__ is a special method thats get called automatically,
Tk.__init__(self) #whenever you create an object out of this class
#use init to make variables and call certain methods like creating UI
self.timer = [0,0,0] # [minutes ,seconds, centiseconds]
#don't forget the self., so you the whole class knows this object
self.resizeable(0, 0) #make it resizeable to 0 pixels in width and height aka. not resizeable is what I like to do
self.makeui()
def makeui(self):
timeFrame = LabelFrame(root, text='Time Frame', width=1200)
timeFrame.grid(row=2,column=2, sticky=W)
#also rest of the buttons, labels I didn't bother copying
#so on
def start(self): #don't forget to pass in self
global state #define it like self.state in init and no need for global
state = True
print 'Clock Running...'
#define rest of the stuff needed copy/paste, adjust the object names, easy
#to finish do
anyname = Anynameyoulike()
anyname.mainloop()
