The localserver command explained

Essentially the localserver command is Django's native runserver disguised with some specific settings. It runs with the IP address 0.0.0.0 on port 80 with ALLOWED_HOSTS having '*' as a value, in case it wasn't already there.

The code, specifically, looks like this;

settings.ALLOWED_HOSTS.append('*')
args = ['name', 'runserver', '0.0.0.0:80']
execute_from_command_line(args)
