[Answered ]-Django-admin.py startproject mysite not working python 2.7

I think your system is not finding the file django-admin.py. Use cmd and navigate to the directory that contains this file and try to execute the command from there:

python django-admin.py startproject mysite

If it works, I recommend you to create an environment variable (e.g. DJANGO_ADMIN) to point do django-admin.py so you can execute the command below from anywhere:

python %DJANGO_ADMIN% startproject mysite 

EDIT:

Creating an environment variable on Windows XP:

1. Open System in Control Panel.

Creating an environment variable on Windows 8:

Start -> All Apps -> Control panel -> System -> Advanced System Settings -> Advanced -> Environment variables.

You can Follow @AmauryMedeiros answer or you can set a path to system environment variable to C:\Python27\Scripts.

It works…
