Movie Ticket Management System

[Pankaj-Str]

Python Programming Assignment: Movie Ticket Management System

Objective:
Develop a command-line Movie Ticket Management System using Python. This project will help you practice object-oriented programming, data structures, file handling, and basic algorithms.

Requirements:

1. Movie Class:
   Create a class called 'Movie' with the following attributes:

   • title (string)
   • duration (integer, in minutes)
   • rating (string, e.g., "PG", "PG-13", "R")
   • show_times (list of datetime objects)

   Methods:

   • init: Initialize the movie object
   • str: Return a string representation of the movie
   • add_show_time: Add a new show time for the movie
   • remove_show_time: Remove a show time for the movie

2. Theater Class:
   Create a class called 'Theater' with the following attributes:

   • name (string)
   • capacity (integer)
   • movies (list of Movie objects)
   • seats (dictionary mapping show times to lists of available seats)

   Methods:

   • init: Initialize the theater object
   • add_movie: Add a new movie to the theater
   • remove_movie: Remove a movie from the theater
   • display_movies: Show all movies currently playing
   • display_show_times: Show all show times for a specific movie
   • book_ticket: Book a ticket for a specific movie and show time
   • cancel_booking: Cancel a booking for a specific movie and show time

3. TicketSystem Class:
   Create a class called 'TicketSystem' to manage the overall system:

   • theaters (list of Theater objects)

   Methods:

   • init: Initialize the ticket system
   • add_theater: Add a new theater to the system
   • remove_theater: Remove a theater from the system
   • display_theaters: Show all theaters in the system
   • save_to_file: Save the system data to a file
   • load_from_file: Load the system data from a file

4. Main Program:
   Create a main program that does the following:

   • Initializes a TicketSystem object
   • Loads existing data from a file (if available)
   • Presents a menu to the user with the following options:
     a. Add a new theater
     b. Add a new movie to a theater
     c. Display all theaters
     d. Display movies in a specific theater
     e. Book a ticket
     f. Cancel a booking
     g. Save and exit
   • Implements each menu option using the TicketSystem and Theater class methods
   • Saves the system data to a file before exiting

5. Error Handling:
   Implement proper error handling throughout the program. For example:

   • Handle file not found errors when loading data
   • Handle invalid input from users
   • Prevent overbooking of seats
   • Handle cases where a movie or theater doesn't exist

6. Data Persistence:
   Use file I/O to save and load the system data. You can use JSON or pickle for data storage.

Example Usage:

Bonus Challenges (Optional):

1. Implement a user authentication system with different privileges for admins and customers.
2. Add a feature to generate reports (e.g., most popular movies, theater occupancy rates).
3. Implement a simple recommendation system based on user booking history.
4. Create a basic GUI using a library like Tkinter or PyQt.

Submission Instructions:

1. Submit your Python script(s) with clear comments explaining your code.
2. Include a brief README file explaining how to run your program and any dependencies required.
3. If you've implemented any bonus challenges, describe them in your README.

Evaluation Criteria:

• Correct implementation of all required features
• Proper use of object-oriented programming principles
• Effective error handling and input validation
• Code organization, readability, and comments
• Proper file handling for data persistence
• Efficient algorithms for seat allocation and booking management
• Bonus points for implementing extra features or optimizations
