Python3的下的解压tar,tar.gz 与os.walk()获取路径下文件的方法

for parent, dir_names, file_names in os.walk(person_dir):
    for file_name in file_names:
        print file_name

#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", ".")

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")

del ['del2'] ['del2.txt']
del\del2 [] ['del3.txt']
