Notes from miguelgrinberg guide

Part 1

• one "peculiarity is that the routes module is imported at the bottom and not at the top of the script as it is always done. The bottom import is a workaround to circular imports, a common problem with Flask applications."
• routes module: "The routes are the different URLs that the application implements. In Flask, handlers for the application routes are written as Python functions, called view functions"
• running application: flask run

Templates

• keep the logic of your application separate from the layout or presentation of your web pages
