In Python 2.5:

>>> import urlparse
>>> url='http://www.example.com/foo?bar=42&spam=eggs'
>>> parsed_url = urlparse.urlparse(url)
>>> parsed_url.query
'bar=42&spam=eggs'
>>> import cgi
>>> parsed_query = cgi.parse_qs(parsed_url.query)
>>> parsed_query
{'bar': ['42'], 'spam': ['eggs']}

In Python >= 2.6, parse_qs lives in the urlparse module as well.
