Я пытаюсь сделать игру в блэкджек, в которой перед каждым новым раундом программа проверяет, чтобы в колоде было по 7 карт на игрока. А если этого не произойдет, колода очищается, заполняется и перетасовывается. У меня большая часть проблемы снята, но по какой-то причине в начале каждой сделки она несколько раз переставляет колоду, и я не могу понять, почему. Помогите, пожалуйста.
Вот что у меня так далеко:
(P.S. импортированные карты и игровые модули не являются частью проблемы, я уверен, что моя проблема заключается в функции deal () моего класса BJ_Deck.)

Поскольку кто-то решил назвать это «экстрасенсорной отладкой», я пойду дальше и расскажу вам, что такое модули.
Вот модуль карт:

А вот игровой модуль:

пока ответ не в ("y", "n"):

обратный ответ
def ask_number (вопрос, низкий, высокий):

ответ = нет
в то время как ответ не в диапазоне (низкий, высокий):
response = int (raw_input (вопрос))
обратный ответ
если name == " main ":
print «Вы запустили этот модуль напрямую (и не« импортировали »его).»
raw_input ("\ n \ nНажмите клавишу ввода для выхода.")
