Please keep the discussion on the list.

You would go to dictionary.com, see (1) how the words are entered by a
user who is using a web browser, what the names are of each field the
browser is submitting, then (2) look at the returned html page and see
how the actual definition is embedded in there. Then from your
knowledge of (1) you would create an appropriate http request in
python, send it to dictionary.com, get the response and once you know
(2) you write a parser (using elementtree for example) that parses the
response and gets your definition.

HTH,
Daniel
