The zipfile module is pure python. Get a copy of zipfile.py from python 2.6, rename it and distribute it with your own scripts. E.g. (assuming it is saved as zipfile26.py in the same directory as your code):import zipfile26 z = r"C:\zipfile.zip" zf = zipfile26.ZipFile(z, 'r') zf.extractall(etc...)
You could also try subclassing ZipFile (2.5) and adding the extract, extractall and _extract_member methods copied from the 2.6 ZipFile class. Completely untested but something like the following *might* work...import zipfile,os,shutil class ZipFile26(zipfile.ZipFile): def extract(self, member, path=None, pwd=None): """Extract a member from the archive to the current working directory, using its full name. Its file information is extracted as accurately as possible. `member' may be a filename or a ZipInfo object. You can specify a different directory using `path'. """ if not isinstance(member, zipfile.ZipInfo): member = self.getinfo(member) if path is None: path = os.getcwd() return self._extract_member(member, path, pwd) def extractall(self, path=None, members=None, pwd=None): """Extract all members from the archive to the current working directory. `path' specifies a different directory to extract to. `members' is optional and must be a subset of the list returned by namelist(). """ if members is None: members = self.namelist() for zipinfo in members: self.extract(zipinfo, path, pwd) def _extract_member(self, member, targetpath, pwd): """Extract the ZipInfo object 'member' to a physical file on the path targetpath. """ # build the destination pathname, replacing # forward slashes to platform specific separators. # Strip trailing path separator, unless it represents the root. if (targetpath[-1:] in (os.path.sep, os.path.altsep) and len(os.path.splitdrive(targetpath)[1]) > 1): targetpath = targetpath[:-1] # don't include leading "/" from file name if present if member.filename[0] == '/': targetpath = os.path.join(targetpath, member.filename[1:]) else: targetpath = os.path.join(targetpath, member.filename) targetpath = os.path.normpath(targetpath) # Create all upper directories if necessary. upperdirs = os.path.dirname(targetpath) if upperdirs and not os.path.exists(upperdirs): os.makedirs(upperdirs) if member.filename[-1] == '/': if not os.path.isdir(targetpath): os.mkdir(targetpath) return targetpath source = self.open(member, pwd=pwd) target = file(targetpath, "wb") shutil.copyfileobj(source, target) source.close() target.close() return targetpath
