如何在Python类中创建数据结构

class MyDataStructure:
    pass

class MyDataStructure:
    def __init__(self):
        self.data = []

class MyDataStructure:
    def __init__(self):
        self.data = []

    def add_element(self, element):
        self.data.append(element)

    def remove_element(self, element):
        self.data.remove(element)

    def get_elements(self):
        return self.data

my_data_structure = MyDataStructure()
my_data_structure.add_element(1)
my_data_structure.add_element(2)
print(my_data_structure.get_elements())  # 输出: [1, 2]
