How to create a complete compressed tar file using Python?

Question

How to create a .tar.gz file with compression in Python?

Answer 1

To create .tar.gz (aka .tgz ) for the entire directory tree:

 import tarfile 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)) 

Answer 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 compressed tar.bz2 file, simply replace the file extension names ".tar.bz2" and "w: gz" with "w: bz2".

Answer 3

You call tarfile.open with mode='w:gz' , which means "Open gzip for compressed mail."

You will probably want to end the file name ( name argument with open ) with .tar.gz , but this does not affect compression options.

By the way, you usually get better compression with the 'w:bz2' , just as tar can compress even better with bzip2 than it can compress with gzip .

Answer 4

In previous answers, it is recommended to use the python tarfile module to create a .tar.gz file in python. This is obviously a good Python-style solution, although it does have a serious flaw in archiving speed. This question mentions that tarfile about twice as slow as calling a direct command on Linux. In my experience, this estimate is pretty true.

Therefore, for faster archiving, you can use the direct Linux command using the subprocess module:

 subprocess.call(['tar', '-czf', output_filename, file_to_archive]) 

Answer 5

In this Compressing the tar.gz file in an open browsing directory In the solution, 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 directory file compression
