CreditCard类的定义：

class CreditCard:
    def __init__(self,customer,bank,acnt,limit):
        self._customer = customer
        self._bank = bank
        self._acnt = acnt
        self._limit = limit
        self._balance = 0
    def get_customer(self):
        return self._customer
    def get_bank(self):
        return self._bank
    def get_acnt(self):
        return self._acnt
    def get_limit(self):
        return self._limit
    def get_balance(self):
        return self._balance
##    receivales
    def charge(self,price):
        if price + self._balance>self._limit:
            return False
        else:
            self._balance+=price
            return True
##    make payment
    def make_payment(self,amount):
        self._balance-=amount
    
##test Class CreditCard        
if __name__=="__main__":
    wallet = []
    wallet.append(CreditCard('Thanlon','California Finance',
                             '5391 0575 9897 5309',8000))

##    print(wallet)
    for val in range(1,30):

            print('New balance = ',wallet[c].get_balance())
        print()
