This code creates a web application using the py-shiny library. The application has a user interface with three columns. The first column contains two inputs that control the other inputs on the page. The second column contains a set of inputs that are controlled by the first two inputs. The third column contains a set of inputs and a tabset. The server function updates the inputs in the second and third columns based on the values of the first two inputs. The application is run in debug mode.
