## Overview

This is a small Streamlit movie-ticket booking app. Users enter customer and show details, choose seats, meals, and a payment method; the app validates the input, calculates fares, saves the booking, and displays confirmation. Separate menu options search bookings, list bookings, and cancel them by updating status. The runtime is a single file, so the components below are logical responsibilities rather than separate modules. Excerpts do not show every query or the full confirmation path.

Main entry points: [`app.py`](https://github.com/dinatikone123/streamlit_demo1/blob/main/app.py) (Booking app), [`movie_booking.db`](https://github.com/dinatikone123/streamlit_demo1/blob/main/movie_booking.db) (SQLite bookings)
