如何一次解压缩具有多个文件夹/文件的.xz文件? [英] How to decompress a .xz file which has multiple folders/files inside, in a single go?

问题描述

我正在尝试解压缩一个.xz文件，该文件中包含一些推子和文件.我看不到使用lzma模块执行此操作的直接方法.这是我看到的一种解压缩方法:

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

还有其他解压缩该文件的方法，以便它将创建结果文件夹吗?

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

推荐答案

Python 3.3

import tarfile

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

Python 2.7

在Python 2.7中需要 lzma

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('.')
