The gzip module... neverending story

[FrancescO]

Hello!,
I have, another questions!!
How can I zip i list of files? (i have done it, but... the files can't be
readed from winzip and gunzip...)

Wich is the correct usage of the fileobj (4th parameters in the
gzip.GzipFile.. explain..:
GzipFile ([filename[, mode[, compresslevel[, fileobj]]]]) )?

Is the name of the zipfile? what kind of object is it?
i'have try in a lot of ways to call this object, but I'm not "good" to work
it with the 4th parameter please...

HELP ME...!!!!
