声明银行账户类Account，成员变量包括账号、储户姓名、开户时间、身份证号码、存款余额等账户信息，成员方法包括开户、存款、取款、查询（余额、明细）、销户等操作。

以下是银行账户类Account的示例代码：

class Account:
    def __init__(self, account_num, name, id_num, balance=0.0):
        self.account_num = account_num
        self.name = name
        self.id_num = id_num
        self.balance = balance
        self.open_date = datetime.datetime.today()

    def deposit(self, amount):
        self.balance += amount
        print("成功存入%.2f元，当前余额为%.2f元。" % (amount, self.balance))

    def withdraw(self, amount):
        if amount > self.balance:
            print("余额不足，取款失败。")
        else:
            self.balance -= amount
            print("成功取出%.2f元，当前余额为%.2f元。" % (amount, self.balance))

    def query_balance(self):
        print("当前余额为%.2f元。" % self.balance)

    def query_detail(self):
        print("账户信息：")
        print("账号：", self.account_num)
        print("姓名：", self.name)
        print("身份证号码：", self.id_num)
        print("开户时间：", self.open_date.strftime("%Y-%m-%d %H:%M:%S"))
        print("当前余额：%.2f元。" % self.balance)

    def close_account(self):
        self.balance = 0.0
        print("账户已成功销户。")

    @staticmethod
    def create_account():
        account_num = input("请输入账号：")
        name = input("请输入储户姓名：")
        id_num = input("请输入身份证号码：")
        balance = float(input("请输入开户金额："))
        account = Account(account_num, name, id_num, balance)
        print("账户创建成功！")
        account.query_detail()
        return account

使用示例：

# 创建账户
account = Account.create_account()

# 存款
account.deposit(1000.0)

# 取款
account.withdraw(500.0)

# 查询余额和明细
account.query_balance()
account.query_detail()

# 销户
account.close_account()
