[BangPypers] Suggestions over BangPypers Digest, Vol 43, Issue 13

[Subhabrata Banerjee]

Sir,
Over your question I sent a suggestion that you may kindly refer to Alan
Gauld's python Tutorial in http://www.freenetpages.co.uk/hp/alan.gauld/. But
the mail bounced. I sent the mail to bangpypers at python.org  I have joined
the mailing list quite new so I do not know exactly why it bounced. I felt
you are looking for the answer so I gave you a copy. It has nothing to do
other than the answer, so sorry for sending you a copy. But if you can
kindly guide me how to answer in the forum I would be immensely helpful.
Best Regards,
Subhabrata Banerjee.
