AttributeError: 'Myapp' object has no attribute 'label'

[mhd-fauzan]

I made a GUI to be able to mute windows sound. After I created the GUI and the script to control the sound I connected the two. And the program runs successfully. But I want to greatly adjust the sound of windows appearing windows volume percentage. I have made it but an error appears AttributeError: 'Myapp' object has no attribute 'label' in the 138th syntax, namely self.label.configure(text=selection) here I display the code.

Can you please fix it as I need this for a project.
Thank You.

You don't appear to have instantiated a self.label widget, hence the error. You do have a self.label1, maybe you meant to configure that?

As an aside, you should check out the PEP-8. Your naming conventions for some of your methods (e.g. setMasterVolume), are at odds with Python convention.

Also you have:

from customtkinter import filedialog

This looks wrong. The filedialog is part of Tkinter, not CustomTkinter. I would expect to see:

from tkinter import filedialog
