python学习笔记 --- tar文件压缩解压

压缩文件：

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")

解压：

import tarfile
import os
def untar(fname, dirs):
    t = tarfile.open(fname)
    t.extractall(path = dirs) 

if __name__ == "__main__":
    untar("del.tar.gz", ".")

dirs参数为保存的目标文件的路径。
