Help on tkinter module

[upendra]

HI Team,

As am unable to run python code in both google colabs and Visual studio, getting below error tried all basic trouble shooting which has not fixed the issue.
request you to kindly help.

Platform: windows

Error:

Hey! There’s a small typo in your code: instead of tk.tk(), try tk.Tk(). Tkinter is case-sensitive, so Tk is the proper method for the main window. That should fix it if that’s the only issue!

By the way, this happens to the best of us. Typos sneak in everywhere. Let us know how it goes! Link Removed

You can't use tkinter, QT or other GUI frameworks in Google Colab nor on other services, which let run your Code in your Browser. In the case of Google Colab, it seems that the Code runs on the Google Colab backend, which runs Linux. Even if the backend has an active X11/Wayland-Session, it is not able to display the GUI on your computer. It runs on the Google Server.

Here a screenshot:
   

Run your GUI code locally on your Windows System.

HI Watson,

Thank for response..!
tried above recommendation which has not fixed issue yet.
Attaching the code for your reference. please check and let me know where it is going wrong.

Post your code using the python button (insert python)

[deanhystad]

Post code instead of attaching files.

One problem you have is there are two mainloop() calls in your code. mainloop() is a blocking function. It does not complete until you close all the windows in your program. It prevents your program from adding widgets to the main window until you close the main window.

Your code with the extra mainloop() call removed:

HI,

The above code has not worked even after removing additional mail loop in colabs.

Thanks

The code runs fine on my box. Of coarse there is no data input
