A project in Django is a collection of configuration and apps for a particular website. For example, a project could be a blog or a news website. An app in Django is a web application that does something – e.g. a blog app, a polls app, a comments app, an ecommerce app, etc. Each app is a Python package that contains a set of related views, models, URLconfs, and other code.
For example, if you wanted to create a blog website, you would create a project for the blog website. Within the project, you would create separate apps for each of the blog components, such as a blog app, a comments app, a polls app, etc. Each of these apps would then be added to the project, and the project would be responsible for coordinating the different apps.
