Problems with zipfile module...

[Christophe Prevost]

Hi,

I've python 2.0, zlib etc... and when i try to use zipfile i've some
problems

for fch in lch:
 if fch == sys.argv[0]: continue
 print fch
 dt = time.mktime(time.gmtime(os.path.getmtime(fch)))
 if dt < veryold:
  cpt += 1
  if cpt == 1:
   backup = zipfile.ZipFile(zip, "w", "ZIP_DEFLATED")
  backup.write(fch)
if cpt != 0:
 backup.close()
---
Raise:

Traceback (most recent call last):
  File "backup.py", line 16, in ?
    backup = zipfile.ZipFile(zip, "w", "ZIP_DEFLATED")
  File "d:\python\lib\zipfile.py", line 104, in __init__
    raise RuntimeError, "That compression method is not supported"
RuntimeError: That compression method is not supported ZIP_DEFLATED
Exception exceptions.AttributeError: "'ZipFile' instance has no attribute
'fp'" in <method ZipFile.__del__ of ZipFile instance at 00914FDC> ignored

PS: It doesn't append when i use the default compression level (not using
zlib)...
backup = zipfile.ZipFile(zip, "w")
