如何让两个对象实例使用银行账号属性进行通信？

class BankAccount:
    def __init__(self, account_number, balance):
        self.account_number = account_number
        self.balance = balance
    
    def deposit(self, amount):
        self.balance += amount
    
    def withdraw(self, amount):
        if self.balance >= amount:
            self.balance -= amount
        else:
            print("Insufficient funds")
    
    def get_balance(self):
        return self.balance

class Person:
    def __init__(self, name, bank_account):
        self.name = name
        self.bank_account = bank_account
    
    def transfer_funds(self, amount):
        self.bank_account.withdraw(amount)
        # Perform other operations or actions with the transferred funds
    
    def get_balance(self):
        return self.bank_account.get_balance()

# 创建银行账号实例
account1 = BankAccount("1234567890", 1000)
account2 = BankAccount("0987654321", 500)

# 创建对象实例
person1 = Person("Alice", account1)
person2 = Person("Bob", account2)

# 实现账号属性通信
person1.transfer_funds(200)
person2.transfer_funds(100)

# 获取余额
print(person1.get_balance())  # 输出：800
print(person2.get_balance())  # 输出：600
