ZipFile - How to update an existing zip file

[Ian Cook]

Hi,
I'm new to python so please excuse me if this is a 'dumb' question.

I want to use the ZipFile module to UPDATE, rather than append, or
create a new zip file.

Does anyone know how this can be done?

This is a snippet of the code I have now..

try:
zf = zipfile.ZipFile (zfname,mode='a ')
except:
zf = zipfile.ZipFile (zfname,mode='w ')

for name in cutflist:
fp = os.path.join(ro ot,name)
print "adding ",fp,"...",
compresstype = zipfile.ZIP_DEF LATED
if zipfile.is_zipf ile(fp):
compresstype = zipfile.ZIP_STO RED
zf.write(fp,com press_type=comp resstype)
print 'done.'

Thanks in advance.
