完成一个企业员工管理系统(EmployeeManagementSystem)， 员工信息(工号，姓名，性别，职位，月薪)功能点: 1. 员工入职(添加) 2. 调整员工的月薪 3. 查询所有员工 4. 根据员工的工号显示员工信息 5. 删除指定工号的员工 6. 统计一个月发放的总工资

好的，我明白了。以下是一个简单的企业员工管理系统的示例代码：

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

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

    def add_employee(self, emp_id, name, gender, position, salary):
        employee = Employee(emp_id, name, gender, position, salary)
        self.employees.append(employee)

    def adjust_salary(self, emp_id, new_salary):
        for employee in self.employees:
            if employee.emp_id == emp_id:
                employee.salary = new_salary
                break

    def get_all_employees(self):
        return self.employees

    def get_employee_by_id(self, emp_id):
        for employee in self.employees:
            if employee.emp_id == emp_id:
                return employee
        return None

    def delete_employee(self, emp_id):
        for employee in self.employees:
            if employee.emp_id == emp_id:
                self.employees.remove(employee)
                break

    def calculate_total_salary(self):
        total_salary = 0
        for employee in self.employees:
            total_salary += employee.salary
        return total_salary

# 使用示例
ems = EmployeeManagementSystem()

# 添加员工
ems.add_employee(1, 'John', 'Male', 'Manager', 5000)
ems.add_employee(2, 'Alice', 'Female', 'Engineer', 4000)
ems.add_employee(3, 'Bob', 'Male', 'Assistant', 3000)

# 调整员工薪资
ems.adjust_salary(2, 4500)

# 查询所有员工
all_employees = ems.get_all_employees()
for employee in all_employees:
    print(f"工号: {employee.emp_id}, 姓名: {employee.name}, 性别: {employee.gender}, 职位: {employee.position}, 月薪: {employee.salary}")

# 根据工号显示员工信息
employee = ems.get_employee_by_id(1)
if employee:
    print(f"工号: {employee.emp_id}, 姓名: {employee.name}, 性别: {employee.gender}, 职位: {employee.position}, 月薪: {employee.salary}")

# 删除员工
ems.delete_employee(3)

# 统计一个月发放的总工资
total_salary = ems.calculate_total_salary()
print(f"一个月发放的总工资: {total_salary}")

请注意，这只是一个简单的示例，实际的员工管理系统可能需要更多的功能和数据验证。你可以根据自己的需求进行修改和扩展。
