我正在编写一些代码来创建一个未排序的列表,但每当我尝试使用insert方法插入一个列表时,我得到的'方法'对象不是可订阅的错误.不知道如何解决它.谢谢.

class UnsortedList:
    def __init__(self):
        self.theList = list()
    def __getitem__(self, i):
       print(self.theList[i])
    def insert(self, lst):
        for x in lst:
            try:
                self.theList.append(float(x))
            except:
                print("oops")


myList = UnsortedList()
myList.insert[1, 2, 3]

class City:
    def __init__(self, string):
        self._string = string.split(',')
        self._name = self._string[0]
        self._state = self._string[1]
        self._latitude = self._string[2]
        self._longitude = self._string[3]
        self._location = [self._latitude, self._longitude]

    def name(self):
        return self._name

    def location(self):
        return self._location
        self.hand.sort(key=lambda x: x.longitude)

    def __lt__(self, other):
        if self._longitude < other._longitude:
            return True
        if self._longitude > other._longitude:
            return False
        if self._longitude == other._longitude:
            if self._latitude < other._latitude:
                return True
            if self._latitude > other._latitude:
                return False
