    python如何生成tar文件内容

    tarfile包中的.open(name, mode)方法能够以mode指定的方式打开name压缩文件,并返回一个TarFile类对象。调用TarFile对象的extractall(path)方法可以将tar文档解压到path指定的位置。

    import tarfile

    tar = tarfile.open( '*.tar.gz', mode = "r:gz") #"r:gz"表示 open for reading with gzip compression

    tar.extractall(path='temp')  ### 将tar.gz文件解压到temp文件夹下

    tar.close()

    open返回的对象不但可以用来读文档数据('r': reading),还可以写('w': writing),附加('a': appending)。
