[Tutor] Iterating through objects

[GoodPotatoes]

I'm not sure if I've been searching using the correct terms.  After I've iterated through an object, such as a cursor or webpage, how do I get back to the "top"?

e.g.

tutorial from http://www.daniweb.com/code/snippet563.html#

print page1.readlines()

>From this excercise, the first time I read page1 I get all of the lines.  The next time, I only get []. What happens to all of the info after I've read it?

Do I need to again get the info from the web?
page1 = opener1.open(picture_page)
