Created two dropdowns one is for class selection and other is for method selection of that particular class. class name: basic, advance, method selection: basic: add,sub, advance:multiply, division and modulus. currently struck at issue where i select class as basic, it shows basic in method selection dropdown also which is not inteded. thereafter if i select class as basic and in method i select add, class which has to be basic is also getting changed to add. help me out.

Answer 1

You have used same tkinter variable self.combobox for both Combobox widgets.

Remove the line:

self.TCombobox2.configure(textvariable=self.combobox)

Or use another tkinter variable for self.TCombobox2 .
