TICKET BOOKING 

Creating a full-fledged ticket booking app involves a lot of components, including backend servers, databases, user authentication, payment gateways, and more. It would be too extensive to provide a complete working app here. However, I can give you a simplified example of a ticket booking system using Python, where we'll focus on the core functionality of booking tickets for a single event. Keep in mind that a real-world app would require much more robustness and security.

For this example, we'll use the console for input/output. You can extend this code and integrate it with a web framework or GUI library for a more user-friendly interface.

```python

class Event:

    def __init__(self, name, capacity, price):

        self.name = name

        self.capacity = capacity

        self.price = price

        self.available_seats = capacity

class TicketBookingApp:

    def __init__(self):

        self.events = {}

        self.bookings = {}

    def add_event(self, event):

        self.events[event.name] = event

    def show_events(self):

        print("Available Events:")

        for name, event in self.events.items():

            print(f"{name} - Price: ${event.price}, Available Seats: {event.available_seats}")

    def book_ticket(self, event_name, num_tickets):

        if event_name not in self.events:

            print("Event not found.")

            return

        event = self.events[event_name]

        if event.available_seats < num_tickets:

            print("Not enough seats available.")

            return

        total_price = event.price * num_tickets

        print(f"Total Price: ${total_price}")

        confirm_booking = input("Do you want to proceed with the booking? (yes/no): ").lower()

        if confirm_booking == "yes":

            event.available_seats -= num_tickets

            self.bookings[event_name] = self.bookings.get(event_name, 0) + num_tickets

            print("Booking confirmed.")

        else:

            print("Booking canceled.")

    def show_bookings(self):

        if not self.bookings:

            print("No bookings yet.")

            return

        print("Current Bookings:")

        for event_name, num_tickets in self.bookings.items():

            print(f"{event_name} - Tickets Booked: {num_tickets}")

if __name__ == "__main__":

    app = TicketBookingApp()

    event1 = Event("Concert", capacity=100, price=50)

    event2 = Event("Conference", capacity=50, price=100)

    app.add_event(event1)

    app.add_event(event2)

    while True:

        print("\nWelcome to the Ticket Booking App")

        print("1. Show Available Events")

        print("2. Book Tickets")

        print("3. Show Bookings")

        print("4. Exit")

        choice = input("Enter your choice (1/2/3/4): ")

        if choice == "1":

            app.show_events()

        elif choice == "2":

            event_name = input("Enter the name of the event you want to book: ")

            num_tickets = int(input("Enter the number of tickets you want to book: "))

            app.book_ticket(event_name, num_tickets)

        elif choice == "3":

            app.show_bookings()

        elif choice == "4":

            print("Thank you for using the Ticket Booking App.")

            break

        else:

            print("Invalid choice. Please try again.")

```

Please note that this is a basic command-line interface, and in a real-world scenario, you'd build a more sophisticated system with user authentication, event persistence (database), and a better user interface (web app or GUI).

Keep in mind that real ticket booking apps also need to handle concurrency issues, ensure secure payment processing, and implement various validations to ensure data integrity and security.
