import urllib
pagetext = urllib.urlopen("http://www.python.org.html").read()

import urllib
pagetext = urllib.urlopen("http://www.python.org").read()
print pagetext
import urllib
pagetext = urllib.urlopen("http://www.python.org").read()
print pagetext

For Python3 use ...

print(pagetext)

Strange ...

import urllib
pagetext = urllib.urlopen("http://www.python.org").read()
print pagetext
import urllib
pagetext = urllib.urlopen("http://www.python.org").read()
print pagetext

... works just fine with Python 2.5.4

You could try the improved version ...

import urllib2
pagetext = urllib2.urlopen("http://www.python.org").read()
print pagetext

pagetext = urllib2.urlopen("http://www.python.org").read()
print pagetext

It could be the way 'Your_mum' is connected to the internet, maybe there is a filter or firewall somewhere. After all, 'www.Python.com' is a porn site.
