default session interface which uses werkzeug’s securecookie
implementation. The only methods you have to implement are
open_session() and save_session(), the others have
useful defaults which you don’t need to change. This method works

Platforms like Udemy provides a lot of quality courses. Doing courses on websites like Coursera or Udemy can get you certifications which can convey to employers that your flask knowledge is legitimate. It is highly recommended to have some rudimentary knowledge of Python programming language.

You then create a Flask application instance named app. Next, you connect the URL route „/“ to the home() function by decorating it with @app.route(„/“). Functions flask developer like these are commonly referred to as views in Flask. In this case, the home view returns a „Hello, World!“ string that the browser can display.

A list of functions that are called by
handle_url_build_error() when url_for() raises a
BuildError. Each function is called
with error, endpoint and values. If a function
returns None or raises a BuildError, it is skipped. In the preceding code block, you first import the Flask object from the flask package. You then use it to create your Flask application instance with the name app.

Step 5 — Dynamic Routes

A route is automatically registered for
this view at static_url_path if static_folder is
set. The flask object implements a WSGI application and acts as the central

application. Once it is created it will act as a central registry for
the view functions, the URL rules, template configuration and much more.
