Python 控制台员工管理系统：使用数组和面向对象实现

以下是一个简单的控制台版本的员工管理系统的代码示例：

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

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

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

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

    def print_employees(self):
        for employee in self.employees:
            print('ID: {}, Name: {}, Age: {}, Gender: {}'.format(employee.id, employee.name, employee.age, employee.gender))

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

def main():
    system = EmployeeManagementSystem()
    while True:
        print('Employee Management System')
        print('1. Add Employee')
        print('2. Remove Employee')
        print('3. Print Employees')
        print('4. Search Employee')
        print('5. Exit')
        choice = input('Enter your choice: ')

        if choice == '1':
            id = int(input('Enter employee ID: '))
            name = input('Enter employee name: ')
            age = int(input('Enter employee age: '))
            gender = input('Enter employee gender: ')
            employee = Employee(id, name, age, gender)
            system.add_employee(employee)
            print('Employee added successfully!')

        elif choice == '2':
            id = int(input('Enter employee ID: '))
            employee = system.search_employee(id)
            if employee:
                system.remove_employee(employee)
                print('Employee removed successfully!')
            else:
                print('Employee not found!')

        elif choice == '3':
            system.print_employees()

        elif choice == '4':
            id = int(input('Enter employee ID: '))
            employee = system.search_employee(id)
            if employee:
                print('ID: {}, Name: {}, Age: {}, Gender: {}'.format(employee.id, employee.name, employee.age, employee.gender))
            else:
                print('Employee not found!')

        elif choice == '5':
            break

        else:
            print('Invalid choice!')

if __name__ == '__main__':
    main()

此代码示例中，Employee类表示员工，具有ID、姓名、年龄和性别属性。EmployeeManagementSystem类表示员工管理系统，具有添加员工、删除员工、打印员工列表和搜索员工等方法。

在main函数中，通过循环显示菜单选项，并根据用户选择执行相应的操作。用户可以选择添加员工、删除员工、打印员工列表、搜索员工或退出系统。
