Thanks every one for commenting. I guess I misspoke. I meant to say that the group is not necessarily the best for parts of this question, so Subhabrata might not get as enthusiastic responses as in some other lists (which i don't recollect at the moment, sorry). I didn't want to convey the sense that his question is not welcome, rather that it might not get a lot of answers.
Thanks Brendon and Steve for the support, and thanks Mark for correcting my slip. Regards, k -- http://mail.python.org/mailman/listinfo/python-list
