David,
Yep, use [::-1] operator ([:] operator with a negative step):l=[1,2,3,4] for i in l[::-1]:print i 4 3 2 1 Explanation in the Python library doc: http://docs.python.org/lib/typesseq.html The Python doc (http://docs.python.org/) is very useful. Most of the time, the thing you are looking for are either in the Language Reference (http://docs.python.org/ref/ref.html) or in the Library Reference (http://docs.python.org/lib/lib.html).
Yes thanks for the info. I was mostly looking at http://docs.python.org/tut/tut.html
BTW, please note that there is no guarantee of the demexp server to sort the list in a specific order (the current reverse order comes from the current sequence of processing in the server, that might change in the future). Each question contains its question number (parameter q_id, qu['q_id'] in your code) and you should sort the list according to that.
Yes, I was thinking about that. There is also a method to retrieve questions by their IDs, right? Do you have any comments on which method is preferable? (or not)
Lyu.
