I am trying to make a script for unzipping all the .tar.gz files from folders in one directory. For example, I will have a file which it calls ( testing.tar.gz). Then if I do manually, I can press to "extract here" then the .tar.gz file will create a new file, and it calls testing.tar. Finally, if I repeat the process of pressing "extract here", the .tar file prodcudes me all the .pdf files.
I wonder that how can I do it, and I have my code here and it seems doesn't realty work tho.
import os
import tarfile
import zipfile
def extract_file(path, to_directory='.'):
if path.endswith('.zip'):
opener, mode = zipfile.ZipFile, 'r'
elif path.endswith('.tar.gz') or path.endswith('.tgz'):
opener, mode = tarfile.open, 'r:gz'
elif path.endswith('.tar.bz2') or path.endswith('.tbz'):
opener, mode = tarfile.open, 'r:bz2'
else:
raise ValueError, "Could not extract `%s` as no appropriate extractor is found" % path
cwd = os.getcwd()
os.chdir(to_directory)
try:
file = opener(path, mode)
try: file.extractall()
finally: file.close()
finally:
os.chdir(cwd)
Why do you want to "press" twice to extract a .tar.gz, when you can easily do it once? Here is a simple code to extract both .tar and .tar.gz in one go:
import tarfile
if fname.endswith("tar.gz"):
tar = tarfile.open(fname, "r:gz")
tar.extractall()
tar.close()
elif fname.endswith("tar"):
tar = tarfile.open(fname, "r:")
tar.extractall()
tar.close()
