By default, a local server is started on port 8000. Visit http: // 127.0.0.1: 8000/in the browser on the local machine. A django welcome page is displayed, indicating that the server is successfully started.

If you want other computers to access this page, run the following command:

Python manage. py runserver 0.0.0.0: 8000
