htmlentities, htmlspecialchars

[Gandalf]

Hi all! I'm writting a web application using IIS and Python. I would 
like to have the Python equvalient of the PHP functions 'htmlentities' 
and 'htmlspecialchars'. E.g. to convert

  a'   >>>>  aacute; 
  ő  >>>>    otilde;

and the others. I looked for them in many libraries (urllib, htmllib, 
urlparse etc.) but I could only find the 'urlencode' function. I could 
not find anything on google  ('python htmlentities equvalent'). Please 
help me find it out. Thanks in advance.
