Python - Get Result of Google Search

My goal is to create a small sript that find all the result of a google search but in "raw".
I don't speak english very well so i prefer to give an exemple to show you what i would like :
I Type : elephant
The script return
www.elephant.com
www.bluelephant.com
www.ebay.com/elephant
.....

I was thinking about urllib.request but the return value will not be usable to that ! I found some tutorials but not adapted at all to my wish ! Like i told you my goal is to have an .txt file as output witch contains alls the website who match with my query !
Thanks all
