18. Problem To Create Employee Management System Using Python

In this Python oops program, we will create an employee management system using Python. This example demonstrates a basic implementation of an employee management application using Python with the help of the below-given steps.

Employee management system using Python

Steps to solve the program

The Employee class represents an employee and has attributes like emp_id, name, and salary. The __init__ method initializes these attributes.
It also has a method called display_details that prints the employee’s ID, name, and salary.
The EmployeeManagementApp class represents the employee management application. It has an attribute called employees which is a list to store instances of the Employee class.
It provides methods to add and remove employees from the application using the add_employee and remove_employee methods.
The display_all_employees method iterates over the list of employees and calls the display_details method for each employee to print their details.
The remaining part of the code demonstrates the usage of the employee management application:
An instance of the EmployeeManagementApp class is created.
Instances of the Employee class are created with different employee IDs, names, and salaries.
Employees are added to the application using the add_employee method.
Finally, the display_all_employees method is called to display the details of all employees in the application.

				
					class Employee:
    def __init__(self, emp_id, name, salary):
        self.emp_id = emp_id
        self.name = name
        self.salary = salary
    
    def display_details(self):
        print("Employee ID:", self.emp_id)
        print("Name:", self.name)
        print("Salary:", self.salary)

class EmployeeManagementApp:
    def __init__(self):
        self.employees = []
    
    def add_employee(self, employee):
        self.employees.append(employee)
    
    def remove_employee(self, employee):
        if employee in self.employees:
            self.employees.remove(employee)
    
    def display_all_employees(self):
        for employee in self.employees:
            employee.display_details()

# Create an instance of the EmployeeManagementApp class
app = EmployeeManagementApp()

# Add employees to the application
employee1 = Employee(1, "Robert Yates", 50000)
employee2 = Employee(2, "Kelly Smith", 60000)
employee3 = Employee(3, "Michael Potter", 55000)

app.add_employee(employee1)
app.add_employee(employee2)
app.add_employee(employee3)

# Display all employees in the application
app.display_all_employees()

Output:

				
					Employee ID: 1
Name: Robert Yates
Salary: 50000
Employee ID: 2
Name: Kelly Smith
Salary: 60000
Employee ID: 3
Name: Michael Potter
Salary: 55000
