Problem in reading a URL

[scum]

This is not a python problem.  That is the text of the site when you go
to it.  The site uses cookies to store a session of your visit.  Using
python bypasses that cookie and throws an error.  You will be better
served using teh mechanize library.

http://wwwsearch.sourceforge.net/mechanize/

Even though you may not get far, since the site you are attempting to
search prevents robots from scouring their site.

>>> import mechanize
>>> from mechanize import Browser
>>> br= Browser()
>>> br.open("http://www.ncbi.nlm.nih.gov/entrez/")
