Boost Your Python Skill with an Employee Management System in 8 Steps

Python is an incredibly powerful and versatile programming language that has gained popularity for its simplicity and ease of use. Whether you’re managing a small business or building complex data-driven applications, Python provides the tools you need to get the job done. One of the best ways to sharpen your Python skills is by working on practical projects that solve real-world problems.

In this blog, we’ll explore an Employee Management System built with Python. This system allows you to perform essential tasks like adding, updating, deleting, and displaying employee records. We will cover this project in a step-by-step manner, understanding all the functions and the flow of the program.

Whether you’re a beginner looking to solidify your programming skills or an experienced developer seeking to refresh your knowledge, this blog will guide you through creating a simple yet effective Employee Management System in Python.

We will start the code by defining all the functions first:

1. Python Variable to handle data of all employees

We will create a variable list_of_employees that will be an empty list that will store the data of the employees in multiple dictionaries.

Copy
list_of_employees = []
Python

2. Function to add employee

In this function, we will receive data on the employee’s ID, name, age, position, and salary from the user. After that, we will check if the ID, inputted by the user is unique or not, and then we will store all the data in a dictionary and add that dictionary to the list_of_employees.

Copy
def add_employee():
    check=True
    print('Enter Employee Details')
    id=int(input('ID:'))
    name=input('Name:')
    age=input('Age:')
    position=input('Position:')
    salary=int(input('Salary:'))
    
    # This portion will be responsible to check the uniqueness of the id.
    if not list_of_employees:
        check=True
    else:
        for employee in list_of_employees:
            if id==employee['id']:
                check=False
                break
    
    # This portion will create a dictionary of all the data and add that dictioanry into the list
    if check==True:
        employee={
            'id':id,
            'name':name,
            'age':age,
            'position':position,
            'salary':salary
        }
        list_of_employees.append(employee)
        print('Employee added successfully')
    else:
        print('ID already exists.')
Python

3. Function to update employees:

This function will be responsible for taking the ID from the user, checking if the ID exists in the data, and then showing the options to update like name, position, and salary. The user will again select an option to update. The program will show the old data, receive new data, and update the data in the list_of_employees variable. If the ID is not present in the variable, it will print ’employee not found.

Copy
def update_employee():
    id=int(input('Enter ID:'))
    for employee in list_of_employees:
        if id == employee['id']:
            print('Which information you want to update:')
            print('1. Name')
            print('2. Position')
            print('3. Salary')
            ch=input('Select any one to update:')
            if ch=='1':
                print(f'Name:{employee['name']}')
                employee['name']=input('Enter new name:')
            elif ch=='2':
                print(f'Position:{employee['position']}')
                employee['position']=input('Enter new position:')
            elif ch=='3':
                print(f'Salary:{employee['salary']}')
                employee['salary']=input('Enter new salary:')
            else:
                print('Invalid choice.')

            print('employee detail updated successfully')
            print()
            return
    print('Employee not found')
Python

4. Function to delete employee: This function will receive the ID from the user, check if it exists or not, and delete the complete dictionary that holds all the data of that particular ID. If the ID is not present in the variable, it will print ’employee not found.

Copy
def delete_employee():
    id = int(input('Enter ID:'))
    for employee in list_of_employees:
        if id == employee['id']:
            list_of_employees.remove(employee)
            print('Employee deleted successfully')
            return
    print('Employee not found')
Python

5. Function to display employees: This function will help us to display the details of all the employees in a tabular format. It will check first for the data in the variable and then start printing the details otherwise it will show no employee to display.

Copy
def display_employees():
    if len(list_of_employees)==0:
        print('No employee to display')
        return
    print('ID \t\t Name \t\t Age \t\t Position \t\t Salary')
    for employee in list_of_employees:
        print(f'{employee['id']} \t\t {employee['name']} \t\t {employee['age']} \t\t {employee['position']} \t\t {employee['salary']}')
Python

Save all these functions in a Python file-like myfunc.py.

Integrating the functions in another Python file:

1. Importing the functions from myfunc.py: We need access to all the functions from the myfunc.py file.

Copy
from myfunc import *
Python

2. Creating an infinity loop and printing all the options: Now we will create an infinity loop using while, print the title of the project, and the options available to the users.

Copy
while True:
    print()
    print("----Employee Management System-----")
    print()
    print("1. Add Employee")
    print("2. Update Employee")
    print("3. Delete Employee")
    print("4. Display Employees")
    print("5. Exit")
    print()
Python

3. Asking the user to select any one operation: In this part, we will ask the user to select any one option and perform the task as per the user by calling the function. The last option will be to exit from the loop. If the user selects an option other than 1-5, it will display an invalid option.

Copy
choice = input("Select anyone: ")
    if choice == '1':
        add_employee()
        print()
    elif choice == '2':
        update_employee()
        print()
    elif choice == '3':
        delete_employee()
        print()
    elif choice == '4':
        display_employees()
        print()
    elif choice == '5':
        print('Exit from program')
        break
    else:
        print("Invalid Option.")
Python
