running python files from command line.
<p>Hi! I'm aware that there are already many topics here asking the same problem but i didn't quite understand them.</p> 

<p>I have a client.py file (location: C:\Users\Sten Sootla\Documents\Chess project\client.py) and i'm trying to run it in my command prompt, but it always gives me an error. I'm using windows 7 and i've already modified my path variable so when i type 'python' in my command line, it starts the interpreter.</p>

<p>Thank you</p>
