Don't you need to provide for that %s? Perhaps
cmd="/usr/bin/transmission-remote --torrent %s --info" % torrentno
As coded, you are passing a TUPLE of two strings as cmd (fyi: the %s will
take the string representation of whatever is the matching argument on the
right, so str() isn't needed -- and if you need a number for both --torrent
and --info you'll need another %s, and (torrentno, torrentno) on the right)
