My server has Python preinstalled, so I thought it could run flawlessly.

However when I try to execute it I get this error
"" file "lswww.py", line 21, in ?
import HTMLParser,urllib,urllib2,cookielib
ImportError: No module named cookielib ""

Does it mean that I need to install any extra module in PYTHON?
