As others have inferred from this question, you're presumably looking
for a way of interpreting the URL's parameters within Python, right?

I believe "request parameters" is the best term to use here.

Well, your URL will pass two parameters to a resource exposed as
"mypage.jsp" (which could actually be a Python script given the
appropriate Web server configuration, although I suppose you're using
a JSP resource as an example of how you'd do it with Java/JSP); these
parameters would be "parm1" and "parm2", and I suppose you'd use the
Java Servlet API methods getParameter or getParameterValues to get the
associated values which are "something" and "another" respectively for
the specified parameters.

Now, in Python, it really depends on your chosen technology as to how
you get those values. Anything vaguely based on the cgi module
( will require you to get
hold of a FieldStorage object and then to use the getvalue method on
it, although care has to be taken about the result and whether it's a
list or not (since you can have many values for a given parameter

In WebStack (
I've tried to standardise this kind of thing, even converting
parameter values from POST requests to Unicode in order to remove
difficulties when actually using such values later on, but on matters
of standardisation the Web-SIG remains silent, so I wouldn't expect
the confusing situation to remedy itself any time soon.
