为上述代码按增添门铃类并将按照管理员类和雇员类进行划分和重新整合

好的，根据你的需求，我来给你编写一下增加门铃类并整合管理员类和雇员类的代码：

class Doorbell:
    def __init__(self):
        self.ring = False

    def press(self):
        self.ring = True


class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age


class Employee(Person):
    def __init__(self, name, age, id_num):
        super().__init__(name, age)
        self.id_num = id_num

    def clock_in(self):
        print(f"{self.name} clocked in.")

    def clock_out(self):
        print(f"{self.name} clocked out.")


class Manager(Employee):
    def __init__(self, name, age, id_num, department):
        super().__init__(name, age, id_num)
        self.department = department

    def add_employee(self, employee):
        print(f"{employee.name} has been added to {self.department} department.")

    def remove_employee(self, employee):
        print(f"{employee.name} has been removed from {self.department} department.")

    def promote_employee(self, employee):
        print(f"{employee.name} has been promoted to a higher position.")


class SecurityGuard(Employee):
    def __init__(self, name, age, id_num, monitor_area):
        super().__init__(name, age, id_num)
        self.monitor_area = monitor_area

    def monitor(self):
        print(f"{self.name} is monitoring {self.monitor_area}.")


class Receptionist(Employee):
    def __init__(self, name, age, id_num, phone_num):
        super().__init__(name, age, id_num)
        self.phone_num = phone_num

    def answer_phone(self):
        print(f"{self.name} is answering the phone.")


class Administrator(Employee):
    def __init__(self, name, age, id_num, department):
        super().__init__(name, age, id_num)
        self.department = department

    def manage_schedule(self):
        print(f"{self.name} is managing the schedule for {self.department} department.")


class Building:
    def __init__(self):
        self.doorbell = Doorbell()
        self.employees = []

    def add_employee(self, employee):
        self.employees.append(employee)

    def remove_employee(self, employee):
        self.employees.remove(employee)

    def ring_doorbell(self):
        self.doorbell.press()

    def get_employee_count(self):
        return len(self.employees)

在上述代码中，我们增加了一个门铃类 `Doorbell`。然后将管理员类和雇员类进行划分，并添加了 `Administrator` 类。最后，我们将 `Building` 类作为整个建筑的入口点，并在其中添加了员工列表和门铃对象。同时，我们还添加了一些方法来管理员工和门铃。
