,可以通过以下步骤实现:
class Vector:
def __init__(self, size):
self.size = size
self.vector = [(None, None)] * size
下面是一个完整的示例代码:
class Vector:
def __init__(self, size):
self.size = size
self.vector = [(None, None)] * size
def add_element(self, index, element):
if index < 0 or index >= self.size:
raise IndexError("Index out of range")
self.vector[index] = element
def get_element(self, index):
if index < 0 or index >= self.size:
raise IndexError("Index out of range")
return self.vector[index]
def remove_element(self, index):
if index < 0 or index >= self.size:
raise IndexError("Index out of range")
self.vector[index] = (None, None)
def modify_element(self, index, element):
if index < 0 or index >= self.size:
raise IndexError("Index out of range")
self.vector[index] = element
# 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")
这个类可以用于存储用户给定大小的类型对列表,并提供了添加、获取、删除和修改元素的功能。
