脚本：

#!/usr/bin/env python
# encoding utf-8
import os
import types

Driver = "d:"
# 输出D盘下的所有文件
for  i  in os.walk(Driver + os.sep + "python-study"):
	print (type(i))
	print (i)	

输出结果

<class ‘tuple‘>

(‘d:\\python-study‘, [], [‘1.txt‘, ‘a.py‘, ‘a1.py‘, ‘a2.py‘, ‘a3-for.py‘, ‘a4.-createFile.py‘, ‘a5-r

eadFile.py‘, ‘a6.py‘, ‘a7.py‘, ‘att2.py‘, ‘attac.py‘, ‘configfile.py‘, ‘dict.py‘, ‘lock.txt‘, ‘mail.

properties‘, ‘mail.py‘, ‘mailConfig.ini‘, ‘scocket.py‘, ‘sendmail.zip‘, ‘sendmail_linux.py‘, ‘sendma

il_win.py‘])

os.path.join()方法取出每个文件绝对路径

#!/usr/bin/env python
# encoding utf-8
import os

Driver = "d:"

for root,dir,file  in os.walk(Driver+ os.sep + "python-study"):
	for i in file:
		full_path = os.path.join(root,i)
		print (full_path)	

D:\python-study>dict.py

d:\python-study\1.txt

d:\python-study\a.py

d:\python-study\a1.py

d:\python-study\a2.py

d:\python-study\a3-for.py

...

os.path.getsize（）方法获取文件大小

#!/usr/bin/env python
# encoding utf-8
import os

Driver = "d:"

for root,dir,file  in os.walk(Driver+ os.sep + "python-study"):
	for i in file:
		full_path = os.path.join(root,i)	
		filesize = os.path.getsize(full_path)
		print (full_path, filesize)
