making django server accessible in LAN

Running the Django Development Server
This is what you're looking for. To help you further, here is what you should do:

python manage.py runserver 0.0.0.0:8000

By the way, this may be a duplicate of this question.

Here is what the documentation says:

Note that the default IP address, 127.0.0.1, is not accessible from other machines on your network. To make your development server viewable to other machines on the network, use its own IP address (e.g. 192.168.2.1) or 0.0.0.0.

To add to @Depado 's answer you may need to add your LAN IP address to ALLOWED_HOSTS in the settings.py along with localhost. it would look like,

ALLOWED_HOSTS = ["localhost", "192.168.8.160"]

(if localhost isn't working use 127.0.0.1 as suggested by @Sabito 錆兎)
