class Bank:
    def __init__(self,name="New Bank"):
        self.name = name
        self.accounts = []
    def add_account(self,x):
        self.accounts.append(x)

class Account:
    def __init__(self,name="New Account",account_holder=None):
        self.amount = 0
        self.name = name
        self.account_holder = account_holder
    def withdraw(self,x):
        self.amount -= x
    def deposit(self,x):
        self.amount += x
    def __repr__(self):
        return str({
            "name": self.name, 
            "amount": self.amount, 
            "account_holder": self.account_holder
            })

chase = Bank("Chase")
print(chase.name)

my_account = Account("Household","Tutorial Doctor")
my_account.deposit(600.00)
my_account.withdraw(100.00)
print(my_account.amount)

chase.add_account(my_account)
