# Generate QR code
generate_ticket_qr(ticket_info, qr_filename)

# Create ticket image with QR code
create_ticket_image(ticket_info, qr_filename, output_filename)

# Explanation:
# •  Install Required Libraries: The qrcode library is used for generating QR codes, and Pillow (PIL) is used for image manipulation.

# •  Generate QR Code: The generate_ticket_qr function creates a QR code from the ticket information and saves it as an image.

# •  Create Ticket Image: The create_ticket_image function creates a ticket image, adds the ticket details, and pastes the QR code onto the ticket.

# This script will generate a ticket image (ticket.png) with the passenger details and a QR code that can be scanned to retrieve the ticket information.

# Feel free to customize the script to fit your specific requirements. If you have any questions or need further assistance, let me know!
