python-3.x - 使用Python银行系统以相同的名称查找多个帐户

Question

在我的银行系统中，我有一组客户帐户，但以亚当·斯密为名，他有两个帐户:

def load_bank_data(self):

    # the customers in the bank system
    account_no = 1234
    customer_1 = CustomerAccount("Adam", "Smith", 14, "Wilcot Street", "Bath", "B5 5RT", account_no, "Current", 2500.00)
    self.accounts_list.append(customer_1)

    account_no += 5678
    customer_2 = CustomerAccount("David", "White", 60, "Holburn Viaduct", "London", "EC1A 2FD", account_no, "Savings", 3200.00)
    self.accounts_list.append(customer_2)

    account_no += 3456
    customer_3 = CustomerAccount("Alice", "Churchil", 55, "Cardigan Street", "Birmingham", "B4 7BD", account_no, "Current", 18000.00)
    self.accounts_list.append(customer_3)

    account_no += 6789
    customer_4 = CustomerAccount("Ali", "Abdallah", 44, "Churchill Way West", "Basingstoke", "RG21 6YR", account_no, "Savings", 40.00)
    self.accounts_list.append(customer_4)

    account_no += 1987
    customer_5 = CustomerAccount("Adam", "Smith", 44, "Churchill Way West", "Basingstoke", "RG21 6YR", account_no, "Savings", 5000.00)
    self.accounts_list.append(customer_5)

我创建了一个函数，以便在找到多个具有相同名字和姓氏的客户帐户时，该功能应该将所有这些银行帐户余额加在一起并打印出最终的总计。 (输入是我输入客户以查找多个帐户的位置:

def sum_of_all_money(self):
    try:

        find_customer = input("Enter the surname of the customer to find total sum of money for: ")

        for find_customer in self.accounts_list:
            find_customer = find_customer.get_balance() + find_customer.get_balance()
        print(find_customer)

    except SyntaxError as e:
        print(e)

这只是在底部找到了一个5号客户的Adam Smith帐户，但并没有将另一个Adam Smith帐户作为客户1进行检测，而只是将5号客户添加了两次，给了我1000.00的输出，这是不对的，我做错了吗？

您的代码有一些缺陷，目前仅会遍历您的列表，并始终用客户的当前余额* 2覆盖find_customer。

您需要过滤输入的正确名称，像这样尝试:

try:

    find_customer = input("Enter the surname of the customer to find total sum of money for: ")

    find_customer_balance = 0

    for customer in self.accounts_list:
        if customer.get_surname() == find_customer:
           find_customer_balance += customer.get_balance()
    print(find_customer)
    print(find_customer_balance)

except SyntaxError as e:
    print(e)
