Attempts: ['my', 'secret', 'password']" >>> make_joint(w, 'hax0r', 'hello') "Your account is locked. Attempts: ['my', 'secret', 'password']"请修改

修改后的代码如下所示：

def make_withdraw(balance, password):
    attempts = []
    def withdraw(amount, pwd):
        nonlocal balance
        nonlocal password
        nonlocal attempts
        if len(attempts) >= 3:
            return "Your account is locked. Attempts: " + str(attempts)
        if pwd != password:
            attempts.append(pwd)
            return "Incorrect password"
        if amount > balance:
            return "Insufficient funds"
        balance = balance - amount
        return balance
    return withdraw

def make_joint(withdraw, old_password, new_password):
    attempts = []
    result = withdraw(0, old_password)
    if result == "Incorrect password" or result == "Your account is locked. Attempts: ['{}']".format(old_password):
        return result
    def joint(amount, pwd):
        nonlocal attempts
        if len(attempts) >= 3:
            return "Your account is locked. Attempts: " + str(attempts)
        if pwd == old_password or pwd == new_password:
            return withdraw(amount, old_password)
        else:
            attempts.append(pwd)
            return withdraw(amount, pwd)
    return joint

修改后的代码主要进行了如下几个方面的修改：

1. 在 `make_joint` 函数中，增加了对原始账户密码错误或者已经被锁定的情况的处理。
2. 在返回结果时，增加了对账户被锁定的情况的处理，使得输出符合要求。
