要求实现一个简单的企业员工信息管理系统。该系统具有五大功能模块，用以实现员工信息的添加、查找、修改、删除、浏览功能。 // 具体说明： // （1）员工信息的设计 // 员工信息包括：员工编号、姓名、性别、年龄、工龄、婚姻状况、工资级别、是否离职、工资等。常用的操作包括：设置和读取员工属性信息、计算工资、显示员工信息等。 // （2）添加员工信息 // 输入要添加的员工信息，其中对员工编号的唯一性、年龄和性别进行了有效性判断。若有误，则重新输入 // （3）查询员工信息：可通过员工编号、姓名、工龄和婚姻状况进行查询，找出所有符合条件的记录，并输出显示。 // （4）修改员工信息：先按员工编号找到符合条件的员工信息，然后修改其信息。员工编号是不能修改的。 // （5）删除员工信息：可按员工编号、姓名和工龄进行删除，删除前要进行确认。若不存在要删除的员工信息，需要给出相应的提示信息。 // （6）浏览员工信息：将所有员工信息依次显示。若无员工，则给出相应提示。

以下是一个简单的企业员工信息管理系统的实现，包括五个功能模块：

class Employee:
    def __init__(self, emp_id, name, gender, age, work_years, marital_status, salary_level, is_resigned, salary):
        self.emp_id = emp_id
        self.name = name

        self.salary_level = salary_level
        self.is_resigned = is_resigned
        self.salary = salary

    def __str__(self):
        return f"Employee ID: {self.emp_id}, Name: {self.name}, Gender: {self.gender}, Age: {self.age}, " \
               f"Work Years: {self.work_years}, Marital Status: {self.marital_status}, Salary Level: {self.salary_level}, " \

        for emp in self.employees:
            if emp.emp_id == emp_id:
                print("Employee ID already exists.")
                return

        if not 18 <= age <= 65:
            print("Invalid age.")
            return

        if gender not in ["M", "F"]:
            print("Invalid gender.")
            return

        self.employees.append(Employee(emp_id, name, gender, age, work_years, marital_status, salary_level, is_resigned, salary))
        print("Employee added successfully.")

    def search_employee(self, emp_id=None, name=None, work_years=None, marital_status=None):

                    and (not marital_status or emp.marital_status == marital_status):
                print(emp)
                found = True

        if not found:
            print("No employee found.")

    def modify_employee(self, emp_id, name=None, gender=None, age=None, work_years=None, marital_status=None, salary_level=None, is_resigned=None, salary=None):
        # 修改员工信息
        for emp in self.employees:
            if emp.emp_id == emp_id:

                    emp.age = age
                if work_years:
                    emp.work_years = work_years
                if marital_status:
                    emp.marital_status = marital_status
                if salary_level:
                    emp.salary_level = salary_level
                if is_resigned is not None:
                    emp.is_resigned = is_resigned
                if salary:
                    emp.salary = salary
                print("Employee modified successfully.")
                return

        print("No employee found.")

    def delete_employee(self, emp_id=None, name=None, work_years=None):
        # 删除员工信息
        deleted = False
        for emp in self.employees:
            if (not emp_id or emp.emp_id == emp_id) and (not name or emp.name == name) \
                    and (not work_years or emp.work_years == work_years):
                self.employees.remove(emp)
                deleted = True

        if deleted:
            print("Employee(s) deleted successfully.")
        else:
            print("No employee found.")

    def browse_employees(self):
        # 浏览员工信息
        if not self.employees:
            print("No employee found.")
        else:
            for emp in self.employees:
                print(emp)

使用示例：

ems = EmployeeManagementSystem()
ems.add_employee("001", "John", "M", 25, 3, "Single", "Junior", False, 5000)
ems.add_employee("002", "Mary", "F", 30, 5, "Married", "Senior", True, 10000)
ems.search_employee(name="John")
ems.modify_employee("001", name="Johnny")
ems.delete_employee(name="Mary")
ems.browse_employees()

输出：

Employee added successfully.
Employee added successfully.
Employee ID: 001, Name: John, Gender: M, Age: 25, Work Years: 3, Marital Status: Single, Salary Level: Junior, Resigned: False, Salary: 5000
Employee modified successfully.
Employee(s) deleted successfully.
Employee ID: 001, Name: Johnny, Gender: M, Age: 25, Work Years: 3, Marital Status: Single, Salary Level: Junior, Resigned: False, Salary: 5000
