Creating the Flask Project

00:00 With your environment set up, let’s create the actual Flask project. First, import the Flask class. This line imports the necessary class to create your Flask application.

00:12 Then, you need to create a Flask app instance. This creates an object named app that represents your web application. The __name__ variable with double underscores before and after it is also called dunder name.

00:25 Dunder is short for double underscores. __name__ is a special variable that holds the name of the current module. It is crucial to determine the root path of the application.

00:36 This allows Flask to locate static files, templates, and other resources. Finally, you need to define a route for your homepage. The app.route() decorator tells Flask to call the index() function when the user visits the root URL.

00:52 The index() function simply returns the string “Hello, World!” and this will be the content displayed on the homepage.

00:59 Now let’s do this in our IDE. Create a new file and call it main.py.

01:13 Here we have imported the Flask class, initialized the Flask object, and created a route for our root URL.
