python is not recognized as an internal or external command duplicate

Question

I recently got Python Version 2.7.5, and I created a little loop with it, however the error I receive when I put python testloop.py in cmd is as follows:

There is no internal or external command that recognises the word "python."

I tried setting the route, but it was ineffective.

Here's my route:

Program Files, in C:

Python27

This is where my Python is set up, as you can see. I'm at a loss on what to do next. Can somebody assist me?
