I\'m trying to extract a .tar file completely using python 2.4.2 and because of this not all of the aspects of the tarfile module are usable. I\'ve looked through the python

Here's the more general code from torchvision library:

import os
import hashlib
import gzip
import tarfile
import zipfile

def _is_tarxz(filename):
    return filename.endswith(".tar.xz")


def _is_tar(filename):
    return filename.endswith(".tar")


def _is_targz(filename):
    return filename.endswith(".tar.gz")


def _is_tgz(filename):
    return filename.endswith(".tgz")


def _is_gzip(filename):
    return filename.endswith(".gz") and not filename.endswith(".tar.gz")


def _is_zip(filename):
    return filename.endswith(".zip")


def extract_archive(from_path, to_path=None, remove_finished=False):
    if to_path is None:
        to_path = os.path.dirname(from_path)

    if _is_tar(from_path):
        with tarfile.open(from_path, 'r') as tar:
            tar.extractall(path=to_path)
    elif _is_targz(from_path) or _is_tgz(from_path):
        with tarfile.open(from_path, 'r:gz') as tar:
            tar.extractall(path=to_path)
    elif _is_tarxz(from_path):
        with tarfile.open(from_path, 'r:xz') as tar:
            tar.extractall(path=to_path)
    elif _is_gzip(from_path):
        to_path = os.path.join(to_path, os.path.splitext(os.path.basename(from_path))[0])
        with open(to_path, "wb") as out_f, gzip.GzipFile(from_path) as zip_f:
            out_f.write(zip_f.read())
    elif _is_zip(from_path):
        with zipfile.ZipFile(from_path, 'r') as z:
            z.extractall(to_path)
    else:
        raise ValueError("Extraction of {} not supported".format(from_path))

    if remove_finished:
        os.remove(from_path)
