Methods

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 usingpath'.

    if not isinstance(member, ZipInfo):
        member = self.getinfo(member)

    if path is None:

    if attr != 0:
        os.chmod(ret_val, attr)
    return ret_val

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().
