Thanks for the reply.

Is it possible to display the duration of time taken for executing the application?

Say ,it should start with 00:00:00, and display the time taken for the aplication.


1) start time

2) Mainn function call

3) End time

In between start and end time ,the time duration has to be displayed.Any suggestions on this.

47 seconds flat:

>>> import datetime as dt
>>> import time
>>> t = time.localtime()
>>> t
(2007, 4, 8, 2, 11, 19, 6, 98, 1)
>>> zeroTime = dt.timedelta(hours=t[3], minutes=t[4], seconds=t[5])
>>> now = dt.datetime(1, 1, 1).now()
>>> now - zeroTime
datetime.datetime(2007, 4, 8, 0, 0, 47, 324000)
>>>

As the application is running ,I would like to display the time duration taken dynamically on the dialog.

Say the appliation started with 00:00:00,as the application started processing the execution then the time display should show the following

00:00:01
00:00:02
......
00:00:47

Every second increment has to be shown in the display at particular location

Sorry, I left this out:

>>> elapsedTime = now - zeroTime
>>> elapsedTime.strftime('%H:%M:%S')
'10:29:09'
>>> 

All the pieces are now here (10 hours, 29 minutes and 9 seconds later).

I've put all the pieces together into a subclass of Label. Simple add this widget to you layout as you would a Tk.Label. Time starts when the widget is created.

from Tkinter import Tk, Label, BOTH
import time
import datetime as dt
 
 
 
class ElapsedTimeClock(Label):
    def __init__(self, parent, *args, **kwargs):
        Label.__init__(self, parent, *args, **kwargs)
        self.lastTime = ""
        t = time.localtime()
        self.zeroTime = dt.timedelta(hours=t[3], minutes=t[4], seconds=t[5])
        self.tick()
 
    def tick(self):
        # get the current local time from the PC
        now = dt.datetime(1, 1, 1).now()
        elapsedTime = now - self.zeroTime
        time2 = elapsedTime.strftime('%H:%M:%S')
        # if time string has changed, update it
        if time2 != self.lastTime:
            self.lastTime = time2
            self.config(text=time2)
        # calls itself every 200 milliseconds
        # to update the time display as needed
        # could use >200 ms, but display gets jerky
        self.after(200, self.tick)
 
 
if __name__ == "__main__":
    root = Tk()
    clock = ElapsedTimeClock(root, font=('times', 20, 'bold'), bg='green')
    clock.pack(fill=BOTH, expand=1)
    root.mainloop()

Thanks Barton,

But where should I have to call my application/main method ,where the time starts before the method call,and it should keep showing the time in mins/secs (some times hrs) untill the method has been executed and come out of the method and display the final time duration .

It should stop showing the time ,once it comes out of the main method of the application/ application executed.

My thinking was that what ever method was being timed would own the GUI.
If that's not the case, remove

self.tick()

and call

myClock.tick()

when you want to start it. You can add a flag to turn the timer on and off in tick().
I'd also add GetElapsedTime() and ResetElapsedTime().
