Hi again.
I want to create a robot or spider or crawler with python urllib. Still couldn't find any good tutorial. Any suggestion?!

check here www.udacity.com

The course project is about making a search engine and building a social network. There is a chapter about web crawlers and ranking web pages using Page Rank algoritm... There is a button 'Access Course Material' just below the 'Start a Free Trial' one and its free.
