基于python链表实现个人资产管理系统

下面是一个简单的基于Python链表的个人资产管理系统：

class Asset:
    def __init__(self, name, value):
        self.name = name
        self.value = value
        self.next = None

class AssetList:
    def __init__(self):
        self.head = None
    
    def add_asset(self, name, value):
        new_asset = Asset(name, value)
        if not self.head:
            self.head = new_asset
        else:
            current = self.head
            while current.next:
                current = current.next
            current.next = new_asset
    
    def remove_asset(self, name):
        if not self.head:
            return "Asset list is empty"
        if self.head.name == name:
            self.head = self.head.next
            return f"{name} removed from asset list"
        current = self.head
        while current.next:
            if current.next.name == name:
                current.next = current.next.next
                return f"{name} removed from asset list"
            current = current.next
        return f"{name} not found in asset list"
    
    def total_value(self):
        if not self.head:
            return 0
        total = 0
        current = self.head
        while current:
            total += current.value
            current = current.next
        return total

    def print_assets(self):
        if not self.head:
            print("Asset list is empty")
        else:
            current = self.head
            while current:
                print(f"{current.name}: ${current.value}")
                current = current.next

上面的代码定义了两个类，一个是`Asset`，表示每一个资产，包括资产名称和价值；另一个是`AssetList`，表示资产列表。`AssetList`中有添加、删除、计算总价值和打印资产列表的方法。这些方法都是基于链表实现的。

下面是一个使用示例：

asset_list = AssetList()

asset_list.add_asset("Savings", 10000)
asset_list.add_asset("Investment", 50000)
asset_list.add_asset("Real Estate", 200000)

asset_list.print_assets()
# Output:
# Savings: $10000
# Investment: $50000
# Real Estate: $200000

print(f"Total value: ${asset_list.total_value()}")
# Output: Total value: $260000

asset_list.remove_asset("Investment")

asset_list.print_assets()
# Output:
# Savings: $10000
# Real Estate: $200000

print(f"Total value: ${asset_list.total_value()}")
# Output: Total value: $210000

在上面的示例中，我们首先创建了一个资产列表`asset_list`，然后添加了三个资产，分别是储蓄、投资和房地产。接着打印了资产列表和总价值。然后，我们移除了投资这个资产，再次打印资产列表和总价值。可以看到，投资这个资产已经被成功移除了。
