我在python中使用while循环运行命令时遇到金额问题

问题描述

我导入了一个json文件，并为超级稻的稻米银行帐户创建了一个while循环。我在父代码下创建def，但遇到错误：TypeError：withdraw_money（）缺少1个必需的位置参数：'amount'。我还尝试为每个子类在新周中添加新值，该值将为超级大米帐户和预付附加500，为普通大米A附加0。由于错误，我被SuperRiceAccount.withdraw_money（amount）困住了，我仍然需要弄清楚新星期的功能。谁能帮我吗？

下面是我的代码

class BaseAccount:
      def __init__(self,account_id,account_type,full_name,birthday,balance,amount=500):
        self.account_id = account_id
        self.account_type = account_type
        self.full_name = full_name
        self.birthday = birthday
        self.balance = balance
        self.amount = amount

    def account_info(self):
        for p in data ['accounts']:
            print('You have successfully withdrawn 500 grams from the account.')
            print('Account ID:' + p['account_id'])
            print('Account Type:' + p['account_type'])
            print('Full Name:' + p['full_name'])
            print('Birthday:' + p['birthday'])
        print('Balance: ' + self.balance + ' left')

    def withdraw_money(self,amount):
        self.balance = self.balance - amount(500)
        for p in data['accounts']:
            print('You have successfully withdrawn 500 grams from the account.')
            print('Account ID:' + p['account_id'])
            print('Account Type:' + p['account_type'])
            print('Full Name:' + p['full_name'])
            print('Birthday:' + p['birthday'])
            print('Balance: ' + self.balance + ' left')

    def new_week(self):
        return

class SuperRiceAccount(BaseAccount):
    def __init__(self,balance):
        super().__init__(account_id,balance)
        if self.balance >= 2000:
            print ('You still have ',self.balance,' left.')
        else:
            print('You do not have enough balance.')

    def new_week(self):
        if initial_balance < 2000:
            self.balance = self.balance + 500
            print('Your new balance is ',' left')

while True:
    print('( 1 ) List All Accounts')
    print('( 2 ) Withdraw Rice from an Account')
    print('( 3 ) New Week')
    print('( 4 ) Exit')
    print('')
   option = int(input('Enter your choice: '))
    if option == 1:
      for p in data['accounts']:
          print('Account ID:'+ p['account_id'])
          print('Account Type:' + p['account_type'])
          print('Full Name:' + p['full_name'])
          print('Birthday:' + p['birthday'])
          print('Balance:'+ str(p["balance"]))
          print('')

    if option == 2:
        print('')
        i = input('Enter Account ID:')
        print('')
        for p in data['accounts']:
            if p ['account_id'] == i:
                print('Account ID:' + p['account_id'])
                print('Account Type:' + p['account_type'])
                print('Full Name:' + p['full_name'])
                print('Birthday:' + p['birthday'])
                print('Balance: ' + str(p["balance"]) + ' left')
                print('')
            else:
                amount = input('Input 500 to withdraw 500 grams from this account:')
                SuperRiceAccount.withdraw_money(amount)
                SuperRiceAccount.account_info(amount)
                for p in data['accounts']:
                    print('Account ID:' + p['account_id'])
                    print('Account Type:' + p['account_type'])
                    print('Full Name:' + p['full_name'])
                    print('Birthday:' + p['birthday'])
                    print('Balance:' + str(p["balance"]))
                    print('')

解决方法

在调用方法SuperRiceAccount时应使用withdraw_money对象。
发生的事情是，当您调用该函数时，金额作为第一个参数self传递，因此第二个参数amount丢失了。


通过初始化对其进行修复：

bank = SuperRiceAccount([PASS HERE INITIALIZATION PARAMETERS])

并致电：

bank.withdraw_money(amount)
bank.account_info(amount)
