Question

So I m just a newbie trying to learn django .. i was just trying to copy what Harry did(a youtuber who teaches code) but I got stuck right after creating the project file, the url.py file of my project keep showing me the error (django.core.exception. improperly configured request settings INSTALLED APP but settings are not config. You must either define the DJANGO_SETTINGS_MODULE or call setting config() before accessing settings.)I tried doing everything I could with the help of Google and YouTube but still not able to solve it . Can someone help me with this

And it's on a mobile ide named pydroid 3.
