Here I am working with two different tkinter frame classes, in which I am trying to access the combobox widget
Now my question is, how can I do so without running into a NameError or AttributeError?
service_list
from the retrieve
frame class, inside a method in the frame class menu
, so that I may configure the values of the combobox.Now my question is, how can I do so without running into a NameError or AttributeError?
