python tarfile模块基本使用

#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()

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

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()
