How to decompress a .xz file which has multiple folders/files inside, in a single go?

问题

I'm trying to uncompress a .xz file which has a few foders and files inside. I don't see a direct way to do this using lzma module. This is what I'm seeing for a decompress method :

In [1]: import lzma

In [2]: f = lzma.decompress("test.tar.xz")
---------------------------------------------------------------------------
error                                     Traceback (most recent call last)
<ipython-input-2-3b08bf488f9d> in <module>()
----> 1 f = lzma.decompress("test.tar.xz")

error: unknown file format

Are there any other methods to un-compress this file so that it will create the resultant folder ?

回答1:

Python 3.3

import tarfile

with tarfile.open('test.tar.xz') as f:
    f.extractall('.')

Python 2.7

Need lzma in Python 2.7

import contextlib
import lzma
import tarfile

with contextlib.closing(lzma.LZMAFile('test.tar.xz')) as xz:
    with tarfile.open(fileobj=xz) as f:
        f.extractall('.')
