Кнопки удаления Tkinter выводят индекс списка ошибок из диапазона

Question

Проблема, с которой я сейчас сталкиваюсь, заключается в том, что при удалении виджетов из окна я получаю сообщение об ошибке, указывающее, что индекс списка выходит за пределы диапазона, и не удаляет все виджеты. Я искал повсюду ответы, но не нашел ни одного, у которого есть моя проблема.

Я сузил его до значения main.py в скрипте запуска GUI класс под функцией usgru, где он говорит:

 for i in range(0, 12):
            if self.usrd == 0:
                self.usrgrubuttons.append(Button(text=buttonNames[i], width='40', command= lambda i=i: thredugm.threader(i)))
                #self.usrgrubuttons.append(Button(text=buttonNames[i], width='40', command=chngTOmm))
                self.usrgrubuttons[i].grid(row=gridrow[i], column=gridcolumn[i], pady='2', padx='5')
            else:
                print(self.usrgrubuttons[i])
                print('starting to delete buttons')
                rmvusrgrubutton(self.usrgrubuttons[i])

Код работает так, как задумано, когда строка, в которой активна команда chngTOmm, но когда команда является лямбда-выражением i = i: tredugm.threader (i) он ломается, и я получаю «список ошибок вне диапазона»

Может кто-нибудь объяснить мне, что я делаю неправильно? Я бы предпочел использовать команду lambda, потому что она запускает команды для всех остальных кнопок.

Любая помощь по этой проблеме будет отличной!

Обновление -------- ------------

Вот вывод ошибки, который я получил:

IndexError: list index out of range

Answer 1

вместо

for i in range(12):

имеют

for i in range(0, len(buttonNames)):

Похоже, что пользователь, который написал код, имел значение 12 в качестве жестко запрограммированного значения по какой-то причине вместо того, чтобы циклически проходить через виджеты независимо от того, где их двенадцать или нет.
