Python fails to run from shell despite being installed and py command running

I am trying to follow the tutorial of setting up an app for Django, but cannot progress past this part;
"python manage.py runserver" from https://docs.djangoproject.com/en/2.2/intro/tutorial01/ 

PS C:\Users\Elias\Documents\WebApp\mysite> ls


    Directory: C:\Users\Elias\Documents\WebApp\mysite

PS C:\Users\Elias\Documents\WebApp\mysite> py ./manage.py runserver 8080

As you can see, Django is installed (but you can only see the version using 'py' and not 'python' for whatever bizarre reason). Even still, 'py ./manage.py runserver' was unable to run a server on either 127.0.0.1 from port 8000 or 8080. All environment variables are setup in
LOCALAPPDATA%\Programs\Python\Python38-32;\%LOCALAPPDATA%\Programs\Python\Python38-32\Lib\site-packages;%LOCALAPPDATA%\Programs\Python\Python38-32\Scripts.

I fixed it by reinstalling python and clicking the option to disable the MAX_PATH character limit on installation.

In your environment variables, you must set up path to the \Python38-32\ only instead of site-packages, the reason is there is apython.exe file there which helps you run thepython manage.py runserver command.

Also make sure you have Django installed, the recommended way is to use a virtualenv, but if you are a beginner it's fine
