在类中将类型对列表的向量大小设置为用户给定的大小

class Vector:
    def __init__(self, size):
        self.size = size
        self.vector = [(None, None)] * size

class Vector:

            raise IndexError("Index out of range")
        self.vector[index] = element

    def get_element(self, index):
        if index < 0 or index >= self.size:

# 示例用法
vector = Vector(5)
vector.add_element(0, ("Type1", "Value1"))
vector.add_element(1, ("Type2", "Value2"))
print(vector.get_element(0))  # 输出：("Type1", "Value1")
vector.remove_element(1)
print(vector.get_element(1))  # 输出：(None, None)
vector.modify_element(0, ("Type3", "Value3"))
print(vector.get_element(0))  # 输出：("Type3", "Value3")
