Great, thanks Diez! Should I just use str(n) to convert it to a format
I can write out to a flat file? I'm also struggling with the strange
date object format that the ODBC module returns when I fetch rows. I
need to convert that to a text string in a format that a mainframe
flatfile database requires. Any advice there?
