Os.walk()与os.path.walk()
os.walk()
函数声明：walk(top,topdown=True,onerror=None)
该函数返回一个元组，该元组有3个元素，这3个元素分别表示每次遍历的路径名，目录列表和文件列表
一般是路径名 和文件列表比较有用
os.walk()实例:
evan@evanpc:~/test$ cat visit.py
#-*- coding:utf-8 -*-
import os,os.path,sys,shutil
def visitdir(path):
for root,dirs,files in os.walk(path):
for filespath in files:
# print filespath
print os.path.join(root,filespath)
if __name__=="__main__":
path="/home/evan/test"
visitdir(path)
#删除某个文件夹（当然可以通过os.listdir的递归调用删除）
#!/usr/bin/env python
#coding=utf-8
import os
def Remove_dir(top_dir):
if os.path.exists(top_dir)==False:
print "not exists"
return
if os.path.isdir(top_dir)==False:
print "not a dir"
return
for dir_path,subpaths,files in os.walk(top_dir,False):
for file in files:
file_path=os.path.join(dir_path,file)
print "delete file:%s" %file_path
os.remove(file_path)
print "delete dir:%s" %dir_path
os.rmdir(dir_path)
#调用
Remove_dir(r"/home/evan/test")
os.path.walk()
evan@evanpc:~/test$ cat visitpa.py
#-*- coding:utf-8 -*-
#功能其实和上面的代码是一样的
import os.path,sys,shutil
def visitdir(arg,dirname,names):
for filespath in names:
# print filespath
# print dirname
print os.path.join(dirname,filespath)
if __name__=="__main__":
path="/home/evan/test"
os.path.walk(path,visitdir,())
os.path.jon
evan@evanpc:~/test$ cat path.join.py
import os
path='/home/evan/test/pytest'
for root, dirs, files in os.walk(path):
for name in dirs:
print os.path.join(root,name)
for file in files:
pass
# print os.path.join(root,name,file)
evan@evanpc:~/test$ python path.join.py
/home/evan/test/pytest/RemoteSystemsTempFiles
evan@evanpc:~/test$ ls pytest/
multi.py mu.py RemoteSystemsTempFiles
evan@evanpc:~/test$ cat path.join.py
import os
path='/home/evan/test/pytest'
for root, dirs, files in os.walk(path):
for name in dirs:
pass
# print os.path.join(root,name)
for file in files:
print os.path.join(root,name,file)
evan@evanpc:~/test$ python path.join.py
/home/evan/test/pytest/RemoteSystemsTempFiles/multi.py
/home/evan/test/pytest/RemoteSystemsTempFiles/mu.py
/home/evan/test/pytest/RemoteSystemsTempFiles/RemoteSystemsTempFiles/.project
总的 删除目录，shutil.rmtree
evan@evanpc:~/test$ cat walk.py
#-*- coding:utf-8 -*-
#删除指定目录的 test.txt 文件 和svn目录
import os.path,sys,shutil
path ='/home/evan/test/pytest'
for root, dirs, files in os.walk(path):
for name in files:
if name=='test.txt':
os.remove(os.path.join(root,name))
for name in dirs:
if name == 'svn':
print name
shutil.rmtree(os.path.join(root,name))
