Python tkinter Labels stop working after some time-CodePudding

I am new to Python and have been trying to create a dashboard that gets data from a php site in json format and then displays the data with tkinter. The application works fine for aprrox. 4 hours but after that the labels duplicate, change position and overlap and the original ones stop updating, I can see in the console that the application is still getting the json data and everything works fine except for the labels (dz, sz, iz, ssz).

How it looks when it works:

        if array[2] > 0:

        else:
            d = array[2]

updateLables(createjson())

CodePudding user response：

The main issue of your code is that it produces each iteration new Labels instead you should configure them. To be more precise, in your current code environment you should have your labels in the global namespace (where you defined your root window). This will allow you to configure them in your function and update the Labels. This way your window and your memory does not get overloaded with Labels you have no use for.

If you need further help on this issue, let me know.
