python学习：递归列出目录里的文件

#!/usr/bin/python

import os

import sys

def print_files(path):

    lsdir = os.listdir(path)

    dirs = [i for i in lsdir if os.path.isdir(os.path.join(path,i))]

    files = [i for i in lsdir if os.path.isfile(os.path.join(path,i))]

    if files:

        for f in files:

            print os.path.join(path, f)

    if dirs:

        for d in dirs:

            print_files(os.path.join(path, d))

print_files(sys.argv[1])

执行：

python 8.py .

显示当前目录下文件
