[Fixed]-Settings.py does not exist django

By default django creates folder named test123 if doesn’t exists, and then puts settings in python package called test123 https://docs.djangoproject.com/en/1.10/ref/django-admin/#startproject

So your settings will be in test123 subfolder of test123

django-admin.py startproject test123
cd test123
ls -la
open test123/settings.py
