A project and an app in Django are two different concepts.
A project is the entire Django web application, including all of its components such as the database, the settings file, the URLs, the views, the templates, and the static files. An example of a Django project is an online store where users can purchase items.
An app is a component of a Django project. It is a self-contained web application that can be reused in multiple projects. An example of a Django app is a blog, which can be added to the online store project mentioned above.
