写一个名为“Bank Of”的银行应用程序。

Bank Of提示输入客户名称和关联的用户名。 Bank Of循环，同时提示：

创建帐户（支票或储蓄）
存款
取款
从支票账户转账到储蓄账户（反之亦然）
显示交易记录。

这是我到目前为止所做的...我需要帮助从chequing转移到储蓄账户..任何帮助将不胜感激。

###MAIN PROGRAM###

printMenu()

Answer 1

我会使用帐户类来跟踪多个帐户：

class Account:
    def __init__(self, accNum):
        self.balance = 0.0
        self.accNum = accNum

    def withdrawl(self, amount):
        self.balance -= amount

    # ETC

然后使用主循环打印选项，输入等等。请注意，由于现在有多个帐户，因此用户必须指定要操作的帐户，可能是帐号。将您的帐户对象存储在列表中，以便找到它们：

if UserRequestsNewAccount:
    new = Account(1234)
    ACCOUNTS.append(new)

然后访问它们：

for acc in ACCOUNTS:
    if acc.accNum == RequestedAccountNumber:
        acc.withdraw(amount)

否则，您可以只有一个双打列表并按索引引用它们。但是不那么有趣。：）

编辑：你的python文件的基本布局应该是这样的：

class Account:
    def __init__(self):
        # fill in code here
    def deposit(self, amount):
        # fill in code here
    def withdraw(self, amount):
        # fill in code here
    def display_history(self):
        # fill in code here

ACCOUNTS = []
def main():
    while 1:
        print "choose an action: 1) new Account \n2) Withdraw .... etc"
        action = raw_input()
        if action == '1':
            print 'enter desired account number: '
            accNum = raw_input()
            new = Account(accNum)
            ACCOUNTS.append(new)
        elif action == '2':
            # fill in code here
        elif action == '3':
            # fill in code here
        elif action == '4':
            # fill in code here

main()

所以我们的想法是声明你的类，然后使用另一个循环来控制这些对象的处理。每个选项都需要一些用户输入来指定要执行的操作，然后调用Account方法。 Account.history可以是一个字符串，您可以在执行操作后附加到该字符串。
