基于python链表实现个人资产管理系统

首先，我们需要定义一个节点类来表示链表中的每个节点：

class Node:
    def __init__(self, date, income, expense):
        self.date = date
        self.income = income
        self.expense = expense
        self.next = None

接下来，我们定义一个链表类来管理节点：

class LinkedList:
    def __init__(self):
        self.head = None

    def add_node(self, date, income, expense):
        new_node = Node(date, income, expense)
        if not self.head:
            self.head = new_node
        else:
            current = self.head
            while current.next:
                current = current.next
            current.next = new_node

    def show_list(self):
        current = self.head
        while current:
            print(f"Date: {current.date}, Income: {current.income}, Expense: {current.expense}")
            current = current.next

现在，我们可以创建一个链表对象并添加节点：

linked_list = LinkedList()
linked_list.add_node("2022-01-01", 1000, 500)
linked_list.add_node("2022-01-02", 1500, 800)
linked_list.add_node("2022-01-03", 2000, 1000)

linked_list.show_list()

输出：

Date: 2022-01-01, Income: 1000, Expense: 500
Date: 2022-01-02, Income: 1500, Expense: 800
Date: 2022-01-03, Income: 2000, Expense: 1000

接下来，我们可以添加其他方法来实现个人资产管理系统，例如计算总收入、总支出、净收入等。
