I am a complete beginner to Python/Django, but I want to dive right in and start experimenting. Thus I was following this guide on installing Python/Django http://devcenter.
If you come across command not found: django-admin.py problem which means you don't installed django frame work. You should install the framework using pip.
pip install django
After that look at the directory if the related script exist or not.
Look into C:\Python27\Scriptsfolder to check for django-admin.py exist or not.
