We'll cover that too. Now it is time to write the corresponding template, which looks like this: Create this file with a single line: Next, the line version: I myself usually start writing small throwaway scripts without any kind of function.
Import the flask module and create an app using Flask as shown: A last word on dynamic routes: This example will also illustrate how we can write helper procedures to generate parts of the page for us.

The complete text of animal. The goal is to see all open items from the ToDo list: This is convenient for development, we create a directory called static inside our project next to main.
In this case we have one line of code which just calls the run method on the application.
Bottle allows you to arrange your code so that one procedure deals with one request; this makes it easy to see what your code is doing and helps with debugging. You are now a successful user of Bottle. Your web app should now be up and running on Heroku.
The first two statements produce no result, but the third produces a count indicating the number of rows inserted.
Then you can invoke the script by name:. Pre-Conference: These half-day sessions are offered on Thursday before the main conference starts, and are available for an additional cost; see the Register page for details.
