How can I create a .tar.gz file with compression in Python?
问题:
回答1:
To build a .tar.gz
(aka .tgz
) for an entire directory tree:
import tarfile
import os.path
def make_tarfile(output_filename, source_dir):
with tarfile.open(output_filename, "w:gz") as tar:
tar.add(source_dir, arcname=os.path.basename(source_dir))
This will create a gzipped tar archive containing a single top-level folder with the same name and contents as source_dir
.
回答2:
import tarfile
tar = tarfile.open("sample.tar.gz", "w:gz")
for name in ["file1", "file2", "file3"]:
tar.add(name)
tar.close()
If you want to create a tar.bz2 compressed file, just replace file extension name with ".tar.bz2" and "w:gz" with "w:bz2".
回答3:
You call tarfile.open with mode='w:gz'
, meaning "Open for gzip compressed writing."
You'll probably want to end the filename (the name
argument to open
) with .tar.gz
, but that doesn't affect compression abilities.
BTW, you usually get better compression with a mode of 'w:bz2'
, just like tar
can usually compress even better with bzip2
than it can compress with gzip
.

Previous answers advise using the tarfile
Python module for creating a .tar.gz
file in Python. That's obviously a good and Python-style solution, but it has serious drawback in speed of the archiving. This question mentions that tarfile
is approximately two times slower than the tar
utility in Linux. According to my experience this estimation is pretty correct.
So for faster archiving you can use the tar
command using subprocess
module:
subprocess.call(['tar', '-czf', output_filename, file_to_archive])

In this tar.gz file compress in open view directory In solve use os.path.basename(file_directory)
with tarfile.open("save.tar.gz","w:gz"):
for file in ["a.txt","b.log","c.png"]:
tar.add(os.path.basename(file))
its use in tar.gz file compress in directory
