Python Course Capstone Individual Project description ✓ Solved

Using Python and the database tool SQLite, you will develop a functionally project of your choice from the Capstone Project List. You will begin with an approach/strategy statement of the project, use the topics covered in class, and document your code using comments inline to the code. Include which project you’re working on in your strategy statement.

Capstone Project List:

  • Airline / Hotel Reservation System

  • Company Manager

  • Patient / Doctor Scheduler

  • Recipe Creator and Manager

  • Flower Shop Ordering To Go

  • Family Tree Creator

  • Quiz Maker

  • Boat Rental

The expectation for this project is you create your own project. You may use the DBbase class code we've used in HW9 and previous assignments. Code from previous assignments may be used as guidance only. Do not copy components from HW9 and submit as your own work.

The project must include multiple components, including functional code, a strategy statement, custom functions, classes, inline comments, data saving/retrieval from a database, inheritance, and an interactive menu.

Paper For Above Instructions

The Python Capstone Course provides students with the opportunity to demonstrate their understanding of key programming concepts through the development of a personal project. For this project, I have chosen to develop an Airline Reservation System. This system will manage flight bookings, track available seating, and generate invoices based on passenger selections.

Project Strategy Statement

My strategy for developing the Airline Reservation System includes the following steps: First, I will outline the main functionalities required, such as the booking interface, payment processing, and seating chart management. Next, I will design the database using SQLite to efficiently store flight and passenger data. Finally, I will implement the project incrementally, ensuring each component works seamlessly before moving to the next phase. I will dedicate significant time to thoroughly document my code to enhance readability and maintainability.

System Design and Components

The Airline Reservation System will be divided into several key components:

  • Database Design: At the core of the system will be an SQLite database that includes tables for flights, bookings, and passengers. This design allows for efficient queries and data retrieval.

  • Class Structure: I plan to utilize Python classes to encapsulate functionality. For example, a Flight class will manage flight details, while a Booking class will handle reservations.

  • User Interface: The system will provide a command-line interface where users can view available flights, make bookings, and process payments. An interactive menu will guide users through various options.

Implementation Plan

The implementation of the Airline Reservation System will follow a structured approach:

  1. Define Requirements: Clearly outline the specifications, focusing on user needs and functional requirements of the booking system.

  2. Set Up Database: Create the SQLite database and implement necessary tables. This includes fields such as flight number, capacity, and passenger details.

  3. Develop Class Hierarchy: Using object-oriented programming principles, I will create base classes such as Flight and Booking, and extend these as needed.

  4. Integrate User Interface: Develop a text-based interface for interacting with the system. This will involve creating a menu system for users to navigate through functionalities.

  5. Testing and Debugging: Regularly test each component of the system. This testing will include unit tests to ensure each function operates correctly.

Code Example and Documentation

Below is a simple implementation of a Flight class that captures essential attributes:



class Flight:


def __init__(self, flight_number, capacity):


self.flight_number = flight_number


self.capacity = capacity


self.booked_passengers = 0


def book_seat(self):


if self.booked_passengers < self.capacity:


self.booked_passengers += 1


return True


else:


return False

This class includes methods to manage flight reservations. Inline comments within the code help clarify functionality, ensuring that other developers can understand the logic behind the implementation.

Data Handling

The system will utilize the SQLite database for persistent data storage. When a booking is made, relevant information, including passenger details and flight number, will be stored in the database to allow for future references or modifications.

An example of saving data into the database can be seen in the following code snippet:



import sqlite3


def save_booking(flight_number, passenger_name):


with sqlite3.connect('airline.db') as conn:


cursor = conn.cursor()


cursor.execute("INSERT INTO bookings (flight_number, passenger_name) VALUES (?, ?)", (flight_number, passenger_name))


conn.commit()

Conclusion

This paper outlines the approach I will take in developing the Airline Reservation System as part of my Python Capstone Project. By creating a user-friendly interface, effectively managing data with SQLite, and adhering to object-oriented principles, I aim to build a robust application that enhances the user experience while learning valuable programming skills.
