人员类，员工类，员工表类的定义和实现，并设计主程序进行测试

以下是人员类、员工类和员工表类的定义和实现，以及主程序的设计和测试。

1. 人员类的定义和实现

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

    def __str__(self):
        return f"{self.name} ({self.gender}, {self.age} years old)"

2. 员工类的定义和实现

class Employee(Person):
    def __init__(self, name, age, gender, id, department, salary):
        super().__init__(name, age, gender)
        self.id = id
        self.department = department
        self.salary = salary

    def __str__(self):
        return super().__str__() + f", {self.department} department, ID:{self.id}, Salary:{self.salary}"

    def increase_salary(self, amount):
        self.salary += amount

3. 员工表类的定义和实现

class EmployeeTable:
    def __init__(self):
        self.employees = []

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

    def remove_employee(self, id):
        for employee in self.employees:
            if employee.id == id:
                self.employees.remove(employee)
                return True
        return False

    def find_employee(self, id):
        for employee in self.employees:
            if employee.id == id:
                return employee
        return None

    def get_all_employees(self):
        return self.employees

4. 主程序设计和测试

# 创建员工表
employees = EmployeeTable()

# 添加员工
employees.add_employee(Employee("Tom", 25, "male", "001", "sales", 5000))
employees.add_employee(Employee("Lucy", 30, "female", "002", "marketing", 6000))
employees.add_employee(Employee("John", 35, "male", "003", "finance", 7000))

# 输出所有员工信息
print("All employees:")
for employee in employees.get_all_employees():
    print(employee)

# 增加员工薪水
employee = employees.find_employee("002")
if employee:
    employee.increase_salary(1000)
    print(f"Employee {employee.id}'s salary increased to {employee.salary}")

# 删除员工
if employees.remove_employee("001"):
    print("Employee 001 removed")
else:
    print("Employee 001 not found")

# 重新输出所有员工信息
print("All employees:")
for employee in employees.get_all_employees():
    print(employee)

输出结果：

All employees:
Tom (male, 25 years old), sales department, ID:001, Salary:5000
Lucy (female, 30 years old), marketing department, ID:002, Salary:6000
John (male, 35 years old), finance department, ID:003, Salary:7000
Employee 002's salary increased to 7000
Employee 001 removed
All employees:
Lucy (female, 30 years old), marketing department, ID:002, Salary:7000
John (male, 35 years old), finance department, ID:003, Salary:7000
