第一种：使用os.walk:

# -*- coding: utf-8 -*-
import os
def Test1(rootDir):
    list_dirs = os.walk(rootDir)
    for root, dirs, files in list_dirs:
        for d in dirs:
            print os.path.join(root, d)
        for f in files:
            print os.path.join(root, f)

    第二种：使用os.listdir:

      # -*- coding: utf-8 -*-
import os
def Test2(rootDir):
    for lists in os.listdir(rootDir):
        path = os.path.join(rootDir, lists)
        print path
        if os.path.isdir(path):
            Test2(path)
