i'm using python 3.5.

you listbox variable local create_widgets since not set self. in order make variable available instance-wide, need contain in self.

change line in create_widgets self.listbox = listbox(self.master, height = 34, width = 30) , change every reference listbox self.listbox in order apply change.

you might want defined self.listbox in __init__(), might keep track of instance variables.
