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(root,name)
print "adding ",fp,"...",
compresstype = zipfile.ZIP_DEFLATED
if zipfile.is_zipfile(fp):
compresstype = zipfile.ZIP_STORED
zf.write(fp,compress_type=compresstype)
print 'done.'

Thanks in advance.
