Django is a web application framework written in Python that emphasizes rapid development and clean methods. Although Django is a web framework, to answer the question whether Django is a front-end or a back-end, you need to have a deep understanding of the concepts of front-end and back-end. The front end refers to the interface that users directly interact with, and the back end refers to server-side programs. They interact with data through the HTTP protocol. When the front-end and back-end are separated, the front-end and back-end programs can be developed independently to implement business logic and interactive effects respectively, and data exchange.
