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,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",".")
