I would not want to let this project collect dust as there is real-world applicability for this application. The reservation system was created with the user in mind so I have no doubt implementing the system into the Hetijetti website would both drive up the sales and enhance customer experience.
I could use a Python web framework like Django or Flask to convert my project into a web application. This would involve restructuring your code to fit into a Model-View-Controller (MVC) architecture, and writing HTML templates for the pages. This way, the Python code could run on the server and generate dynamic content for the Hetijetti website.
