该小型企业的员工主要有 4 类：经理、技术员、销售员和计时工。要求存 储员工的工号、姓名、岗位、月工资等基本信息

可以使用面向对象编程的思想，定义一个员工类，包含工号、姓名、岗位和月工资等属性，然后派生出经理类、技术员类、销售员类和计时工类。具体实现代码如下：

class Employee:
    def __init__(self, id, name, position, salary):
        self.id = id
        self.name = name
        self.position = position
        self.salary = salary

class Manager(Employee):
    def __init__(self, id, name, position, salary, department):
        super().__init__(id, name, position, salary)
        self.department = department

class Technician(Employee):
    def __init__(self, id, name, position, salary, skill_level):
        super().__init__(id, name, position, salary)
        self.skill_level = skill_level

class Salesman(Employee):
    def __init__(self, id, name, position, salary, sales_volume):
        super().__init__(id, name, position, salary)
        self.sales_volume = sales_volume

class HourlyWorker(Employee):
    def __init__(self, id, name, position, salary, hours_worked):
        super().__init__(id, name, position, salary)
        self.hours_worked = hours_worked

以上代码定义了一个员工类和四个派生类，分别表示经理、技术员、销售员和计时工，每个类都继承了员工类的属性，并添加了额外的属性。可以根据具体需求，对这些类进行扩展和修改。
