python tarfile模块基本使用

1.压缩一个文件夹下的所有文件

#coding=utf8
import os
import tarfile

__author__ = 'Administrator'

def main():
    cwd = os.getcwd()
    tar = tarfile.open('test.tar','w:gz')
    for root ,dir,files in os.walk(cwd):
        for file in files:
            fullpath = os.path.join(root,file)
            tar.add(fullpath)

if __name__=='__main__':
    main()

2.解压缩一个tar包

import tarfile
tar = tarfile.open("sample.tar.gz")
tar.extractall()
tar.close()

3.有选择的解压缩一个tar包

import os
import tarfile

def py_files(members):
    for tarinfo in members:
        if os.path.splitext(tarinfo.name)[1] == ".py":
            yield tarinfo

tar = tarfile.open("sample.tar.gz")
tar.extractall(members=py_files(tar))
tar.close()
