python列举文件夹下所有文件行数

    在群里聊天，看到一段代码，是可以统计文件夹下所有文件的行数，觉得不错，记录下来，以备将来有用的时候来派用场，下面贴上代码：

import os 
import fileinput 
dest="/root/log" 
for root,dirs,filename in os.walk(dest): 
    for file in filename: 
        f=os.path.join(root,file) 
        for each in fileinput.input(f): 
            pass 
        print "filename:%s    filenumber:%s" % (fileinput.filename(), fileinput.lineno())  

 下面看下效果：

[root@qhz ~]# python list_number.py
