🐍 ITI Python Final Task

This repository contains the final project for the Python course as part of the ITI scholarship program.
The project demonstrates Object-Oriented Programming (OOP) concepts in Python by simulating a simple office management system with employees, cars, and email validation.

📂 Project Structure

• story.py
  Contains the main classes and logic:

  • Person: Base class for basic attributes and behaviors (sleep, eat, buy).
  • Employee: Inherits from Person, adds work-related methods (work, drive, refuel, send email).
  • Office: Manages employees (hire, fire, check lateness, reward, deduct).
  • Car: Simulates car behavior (run, stop) with fuel and velocity handling.

• email_validator.py
  Contains the email validation function

---

🛠 Features & OOP Concepts

1. Email Validation (email_validator.py)

A standalone function email_validation(email: str) that:

• Checks if the email is not empty.
• Ensures the email starts with an alphabetic character.
• Prevents spaces in the email.
• Validates the format (e.g., example@email.com).

This function is imported and used inside the Employee class to ensure valid emails before assigning them to employees.

2. Class: Person

Base class representing a general person.

• Attributes: name, money, mood, healthRate
• Methods:
  • sleep(hours) → changes mood based on hours slept.
  • eat(meals) → adjusts health rate based on meal count.
  • buy(item_count) → deducts money when buying items.

---

3. Class: Employee (inherits from Person)

Represents an employee with extra attributes and behaviors.

• Extra Attributes: id, car, email, salary, distanceToWork, targetHour
• Extra Methods:
  • work(hours) → updates mood based on working hours.
  • drive() → uses the Car object to simulate driving.
  • refuel(gasAmount) → refuels the car.
  • send_mail(body, to) → sends an email if the employee has a valid email.

Key OOP concept:

• Inheritance from Person to reuse common attributes and methods.
• Composition: Employee "has-a" Car object.

---

4. Class: Office

Manages a collection of employees.

• Attributes: name, employees (dictionary), employees_num (class variable)
• Methods:
  • hire(...) → adds a new employee.
  • fire(id) → removes an employee.
  • get_all_employees() / get_employee(id) → retrieves employee info.
  • check_lateness(...) → checks if an employee is late based on car speed and distance.
  • reward(id, amount) / deduct(id, amount) → updates employee money.
  • change_emps_num(num) → updates total number of employees (class method).

Key OOP concepts:

• Static methods (calculate_lateness) for utility calculations.
• Class methods (change_emps_num) to modify class-level data.

---

5. Class: Car

Represents a car assigned to an employee.

• Attributes: name, fuelRate, velocity, distance
• Methods:
  • run(distance, velocity) → simulates driving until fuel or distance runs out.
  • stop() → stops the car.

Key OOP concept:

• Encapsulation of car behavior inside its own class.

---

💡 OOP Principles Used

• Encapsulation → Grouping related attributes and methods inside classes.
• Inheritance → Employee inherits from Person.
• Composition → Employee has a Car.
• Polymorphism → Methods like sleep() and work() change behavior based on input.
• Static & Class Methods → For operations not tied to a specific object instance.
