Real Time Clock Display In Tkinter

I want to create real time clock using Tkinter and time library. I have created a class but somehow I am not able to figure out my problem. My code from tkinter import * import ti

Solution 1:

Second parameter of after() should be a function -when you are giving any- but you are giving a str object. Hence you are getting an error.

from tkinter import *    
import time

root = Tk()

classClock:
    def__init__(self):
        self.time1 = ''
        self.time2 = time.strftime('%H:%M:%S')
        self.mFrame = Frame()
        self.mFrame.pack(side=TOP,expand=YES,fill=X)

        self.watch = Label(self.mFrame, text=self.time2, font=('times',12,'bold'))
        self.watch.pack()

        self.changeLabel() #first call it manuallydefchangeLabel(self): 
        self.time2 = time.strftime('%H:%M:%S')
        self.watch.configure(text=self.time2)
        self.mFrame.after(200, self.changeLabel) #it'll call itself continuously

obj1 = Clock()
root.mainloop()

Also note that:

The callback is only called once for each call to this method. To keep calling the callback, you need to reregister the callback inside itself.
