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.
To windows users out there: I have faced this problem several times and here are the checkpoints:
When there is problem initiating a new project, make sure:
1) python is working in the command line (type in python and see if you get the console)
2) specify the full path of django-admin.py in the command
3) check django-admin.py is in the system path
4) cd the command line path to where you want the new project
Screenshot of what finally worked for me (only the last command): https://flic.kr/p/r9LJ67 (stackoverflow doesn't allow me to post pictures yet)
