导语：
本文主要介绍了关于python如何生成tar文件内容的相关知识，包括python docx，以及python复制文件到另一个目录这些编程知识，希望对大家有参考作用。
tarfile包中的.open(name, mode)方法可以以mode指定的模式打开name压缩文件，并返回一个TarFile类对象。调用 TarFile 对象的 extractall(path) 方法，将 tar 文件解压到 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 返回的对象不仅可以用于读取文档数据（'r'：读取），还可以用于写入（'w'：写入）和追加（'a'：追加）。
如下是mode取值所对应的含义：
'r' or 'r:*' open for reading with transparent compression
'r:' open for reading exclusively uncompressed
'r:gz' open for reading with gzip compression
'r:bz2' open for reading with bzip2 compression
'r:xz' open for reading with lzma compression
'a' or 'a:' open for appending, creating the file if necessary
'w' or 'w:' open for writing without compression
'w:gz' open for writing with gzip compression
'w:bz2' open for writing with bzip2 compression
'w:xz' open for writing with lzma compression
'x' or 'x:' create a tarfile exclusively without compression, raise
an exception if the file is already created
'x:gz' create a gzip compressed tarfile, raise an exception
if the file is already created
'x:bz2' create a bzip2 compressed tarfile, raise an exception
if the file is already created
'x:xz' create an lzma compressed tarfile, raise an exception
if the file is already created
'r|*' open a stream of tar blocks with transparent compression
'r|' open an uncompressed stream of tar blocks for reading
'r|gz' open a gzip compressed stream of tar blocks
'r|bz2' open a bzip2 compressed stream of tar blocks
'r|xz' open an lzma compressed stream of tar blocks
'w|' open an uncompressed stream for writing
'w|gz' open a gzip compressed stream for writing
'w|bz2' open a bzip2 compressed stream for writing
'w|xz' open an lzma compressed stream for writing本文为原创文章，版权归知行编程网所有，欢迎分享本文，转载请保留出处！
