👨‍💼 Employee Management System

A menu-driven Employee Management System developed using Python Object-Oriented Programming (OOP) and File Handling. This application allows users to manage employee records with features like adding, updating, deleting, searching, and viewing employee details. Employee data is stored permanently using a text file.

📌 Features

  • ➕ Add Employee
  • 📋 View All Employees
  • 🔍 Search Employee by ID
  • ✏️ Update Employee Details
  • ❌ Delete Employee
  • 👥 Employee Count
  • 💰 Display Highest Paid Employee
  • 💸 Display Lowest Paid Employee
  • 📊 Calculate Average Salary
  • 💾 Save Employee Data to Text File
  • 📂 Automatically Load Employee Data on Program Start
  • ✅ Input Validation for Employee Details
  • 🧩 Modular Code Structure

🛠️ Technologies Used

  • Python 3
  • Object-Oriented Programming (OOP)
  • File Handling (open())
  • Text File Storage
  • Exception Handling
  • Modular Programming

3. Search Employee
4. Update Employee
5. Delete Employee
6. Employee Count
7. Highest Paid Employee
8. Lowest Paid Employee

💾 Data Storage

Employee records are stored in employees.txt using comma-separated values.

Example:

101,Pranav S,25,IT,35000.0
102,Sourav P,26,IT,10000.0
103,Sumathi S,27,IT,45000.0

The application automatically:

  • Loads employee data when the program starts.
  • Saves updated data after every Add, Update, or Delete operation.
