Thank you so much.

The only thing I found need to be double checked is doing multiple clicks on start button which makes it faster and faster which will be shorter than the normal second.
All other code looks great, and was really helpful to me.

What is that 'self 'in the code? Can you please explain!! Thank you!

You may use h = str(h).zfill(2) to solving {%d%d} problem
And
elif (m == 59) :
m = 0 ( --> missing)
h += 1
Thank you so much for your video.
Hopefully you can make a Tkinter that having Timer & Stopwatch in different screen function.

The code works good but there is something missing: when you start the timer, this one inmediatelly starts in 00:00:01 but this is wrong because it should take 1 second to show it. But thanks for the help!

Brother there is issue with your code, if you run the timer for about an hour. It starts showing the wrong digit at hour place, check your code again

where is the mainloop() part??? How does this work without that?

I want to create exactly the same thing but I want the stopwatch to stop when I lock my pc and start when I unlock it

Hi, I downloaded your code from the link but when i try to run it, it doesn't show anything (the window doesn't show up) but there's not any syntax error because the debugger tells that everything is fine. Can you tell me if there's something else missing in the code?

[namitmishra]

after minute reaches 59 then you are not doing m = 0 inside hour check

, do you have any idea, thanks ?
