You can do it easily by adding the Python path (in my case C:\Python27) to your system PATH.

Simply go to Control Panel > System > Advanced system settings, select 'Advanced' tab, click 'Environment Variables'.

There you need to add the path to Python (C:\Python27) to the Path BOTH:
- User variables
- System variables
For each one click 'Edit' and paste the path (C:\Python27) at the end of the line with a ';' to separate it

Restart your shell window and it should work!
