如何用Python实现目录遍历

import os
path='/tmp'
for dirpath,dirnames,filenames in os.walk(path):
for file in filenames:
fullpath=os.path.join(dirpath,file)
print fullpath

[root@localhost ~]# python dirfile.py
/tmp/yum.log
/tmp/pulse-3QSA3BbwpQ49/pid
/tmp/pulse-3QSA3BbwpQ49/native
/tmp/.esd-/socket

import os,sys
path=sys.argv[1]
for dirpath,dirnames,filenames in os.walk(path):
for file in filenames:
fullpath=os.path.join(dirpath,file)
print fullpath

import os,sys
path='/tmp'
def paths(path):
path_collection=[]
for dirpath,dirnames,filenames in os.walk(path):
for file in filenames:
fullpath=os.path.join(dirpath,file)
path_collection.append(fullpath)
return path_collection
for file in paths(path):
print file

import os,sys
class diskwalk(object):
def __init__(self,path):
self.path = path
def paths(self):
path=self.path
path_collection=[]
for dirpath,dirnames,filenames in os.walk(path):
for file in filenames:
fullpath=os.path.join(dirpath,file)
path_collection.append(fullpath)
return path_collection
if __name__ == '__main__':
for file in diskwalk(sys.argv[1]).paths():
print file
