Method extract

Lib/tarfile.py:2480–2498

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 TarInfo object. You can specify a different directory using 'path'. File attributes (

(self, member, path="", set_attrs=True, *, numeric_owner=False,
                filter=None)

                  (member.name, reason))

    def extract(self, member, path="", set_attrs=True, *, numeric_owner=False,
                filter=None):

           specify a different directory using 'path'. File attributes (owner,
           mtime, mode) are set unless 'set_attrs' is False. If 'numeric_owner'
           is True, only the numbers for user/group names are used and not
           the names.

           The 'filter' function will be called before extraction.
           It can return a changed TarInfo or None to skip the member.
           String names of common filters are accepted.
