python tarfile模块基本使用

1.压缩一个文件夹下的所有文件

#coding=utf8import osimport 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 tarfiletar = tarfile.open("sample.tar.gz")tar.extractall()tar.close()

3.有选择的解压缩一个tar包

import osimport tarfiledef py_files(members):    for tarinfo in members:        if os.path.splitext(tarinfo.name)[1] == ".py":            yield tarinfotar = tarfile.open("sample.tar.gz")tar.extractall(members=py_files(tar))tar.close()
