我有一個(gè)從列表繼承的類。如何在創(chuàng)建實(shí)例時(shí)分配列表而不是在創(chuàng)建后附加到實(shí)例？示例代碼：class ListObject(list):    def __init__(self, a, b, c):        self.a = a        self.b = b        self.c = cpremade_normal_list = [0, 1, 2, 3, 4, 5, 6]_list = ListObject(1, 2, 3) # Can I explicitly assign the premade list as this                             #  object while retaining attributes?# How I now have to do it.premade_normal_list = [0, 1, 2, 3, 4, 5, 6]_list = ListObject(1, 2, 3)for i in premade_normal_list:    _list.append(i)我試過了，這并不奇怪：class ListObject(list):    def __init__(self, a, b, c, _list):        self = _list        self.a = a        self.b = b        self.c = cpremade_normal_list = [0, 1, 2, 3, 4, 5, 6]_list = ListObject(1, 2, 3, premade_normal_list)我很難解釋，希望它足夠清楚......
