Python下使用tarfile模块来实现文件归档压缩与解压

部分转自：http://www.diybl.com/course/3_program/python/20110510/555345.html

Tarfile.open(cls, name=None, mode='r', fileobj=None, bufsize=10240, **kwargs) method of __builtin__.type instance

Open a tar archive for reading, writing or appending. Return

an appropriate TarFile class.

mode:

'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

'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

'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

'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

1．压缩，创建tar.gz包

#!/usr/bin/env python

import os

import tarfile

#创建压缩包名

tar = tarfile.open("/tmp/tartest.tar.gz","w:gz")

#创建压缩包

for root,dir,files in os.walk("/tmp/tartest"):

for file in files:

fullpath = os.path.join(root,file)

tar.add(fullpath)

tar.close()

2．解压tar.gz包

#!/usr/bin/env python

import tarfile

tar = tarfile.open(“/tmp/tartest.tar.gz”)

names = tar.getnames()

for name in names:

tar.extract(name,path=”/tmp”)
