[Tutor] zip question

[D. Hartley]

P.S.  I realize that zipfile has commands, and zipinfo only seems to
list "attributes."  Each instance of ZipInfo is a collection of
information about the file in the archive: its filename, its comments,
etc.  So filename is not filename() - it's not a callable command. But
how can i access/see this information about a given member of the
archive?
