获取目录下的所有目录（包括各子目录中的目录）

import os
i=0
for root,dirs,files in os.walk('D:\Desktop'):

    for dir in dirs:
        print dir
        i+=1
print i
获取目录下所有文件方法（包括[b]各子目录中的文件[/b]）

import os
i=0
for root,dirs,files in os.walk('D:\Desktop'):

    for f in files:
        print file
        i+=1
print i

for list_all in os.walk("D:\Desktop"):
print list_all
for root,dirs,files in os.walk("D:\Desktop"):
print root,dirs,files
os.walk("D:\Desktop")返回的是生成器

list_all是元组，元组第一项是字符串，为目录路径。元组第二项是列表，是第一项目录中的所有目录（只是第一项次一层的而已）。第三项是一个列表，为该目录中所有的文件。

import os.path
path = '/home/vamei/doc/file.txt'

print(os.path.basename(path))    # 查询路径中包含的文件名
print(os.path.dirname(path))     # 查询路径中包含的目录

info = os.path.split(path)       # 将路径分割成文件名和目录两个部分，放在一个表中返回
path2 = os.path.join('/', 'home', 'vamei', 'doc', 'file1.txt')  # 使用目录名和文件名构成一个路径字符串

p_list = [path, path2]
print(os.path.commonprefix(p_list))    # 查询多个路径的共同部分
os.path.normpath(path)   # 去除路径path中的冗余。比如'/home/vamei/../.'被转化为'/home'

import os.path
path = '/home/vamei/doc/file.txt'

print(os.path.exists(path))    # 查询文件是否存在

print(os.path.getsize(path))   # 查询文件大小
print(os.path.getatime(path))  # 查询文件上一次读取的时间
print(os.path.getmtime(path))  # 查询文件上一次修改
4000
的时间

print(os.path.isfile(path))    # 路径是否指向常规文件
print(os.path.isdir(path))     # 路径是否指向目录文件

import os

print os.listdir("C:\Users\Desktop\packages")

#扩展名是通过os.path.splitext函数提取出来
fname=/Users/justin/Downloads/joomla-3.1.1/home.html

#root, extension = os.path.splitext(fname) 扩展名

#basename = os.path.basename(fname) 文件名

#dirname = os.path.dirname(fname) 目录名

#dirname,basename = os.path.split(fname)
