python 实现tar文件压缩解压的实例详解

import tarfile import os def tar(fname):   t = tarfile.open(fname + ".tar.gz", "w:gz")   for root, dir, files in os.walk(fname):     print root, dir, files     for file in files:       fullpath = os.path.join(root, file)       t.add(fullpath)   t.close()  if __name__ == "__main__":   tar("del") 

import tarfile import os def untar(fname, dirs):   t = tarfile.open(fname)   t.extractall(path = dirs)   if __name__ == "__main__":   untar("del.tar.gz", ".")
