I’m fairly new to python and can’t get a test program functioning. The goal was to create an address book using objects to hold information. The widget runs but when a button is clicked instead of updating I get the error
"Exception in Tkinter callback

Лучший ответ
Я полагаю, вы имеете в виду, что после нажатия кнопки сброса, затем «Открыть файл», и он заполняет ваш список с предыдущими записями? Когда вы выполняете resetList, вы просто удаляете элементы с экрана, но сохраняете заполненный список apps, поэтому при вызове addApp этот список загружается и отображается снова с новым элементом в конце. Это можно исправить, вызвав apps.clear() в функции resetList, которая удалит все записи в apps. — ответ @Talon

Ваша функция resetList делит имя с вашей переменной Button. Вместо вашей функции он пытается вызвать себя.
На этой линии:
resetList = tk.Button(root, text="Reset", padx=10, pady=5, fg="white", bg="#263D42", command=lambda:[removeSave(),resetList()])
Вы используете лямбда-функцию для выполнения функций removeSave и resetList. Проблема в том, что переменная, которой вы назначаете эту кнопку, также называется resetList. Мы можем проверить это, когда заменим вызов функции и вместо этого выведем, что resetList:
resetList = tk.Button(root, text="Reset", padx=10, pady=5, fg="white", bg="#263D42", command=lambda:[removeSave(),print(repr(resetList))])
После исполнения это даст нам <tkinter.Button object .!button3> Вы вызвали свою функцию resetList, но переписали ее с помощью кнопки, которая также называется resetList, поэтому вместо выполнения функции с resetList() ваша программа пытается выполнить кнопку. Это можно исправить, например, переименовав переменную Button, например:
reset_list_button = tk.Button(root, text="Reset", padx=10, pady=5, fg="white", bg="#263D42", command=lambda:[removeSave(),resetList()])
reset_list_button.pack()

You aren’t showing enough code.
Where is your class definition, and the code that calls it ?
Your passing args, but the functions that you are showing don’t receive any
