1.os.popen運行shell列表命令

def traverseDirByShell(path):

for f in os.popen('ls ' + path):

print f.strip()

2.利用glob模塊

glob.glob(path)返回帶目錄的文件名.通配符和shell相似.path不能包含shell變量.

def traverseDirByGlob(path):

path = os.path.expanduser(path)

for f in glob(path + '/*'):

print f.strip()

3.利用os.listdir(推薦)

該方法返回不帶根目錄的文件名或子目錄名

def traverseDirByListdir(path):

path = os.path.expanduser(path)

for f in os.listdir(path):

print f.strip()

4.利用os.walk(推薦)

返回一個包含3個項目的元組:當前目錄名稱,子目錄名稱,子文件名稱

def traverseDirByOSWalk(path):

path = os.path.expanduser(path)

for (dirname, subdir, subfile) in os.walk(path):

#print('dirname is %s, subdir is %s, subfile is %s' % (dirname, subdir, subfile))

print('[' + dirname + ']')

for f in subfile:

print(os.path.join(dirname, f))

整合代碼:

#!/usr/bin/python

import os

from glob import glob

def printSeparator(func):

def deco(path):

print("call method %s, result is:" % func.__name__)

print("-" * 40)

func(path)

print("=" * 40)

return deco

@printSeparator

def traverseDirByShell(path):

for f in os.popen('ls ' + path):

print f.strip()

@printSeparator

def traverseDirByGlob(path):

path = os.path.expanduser(path)

for f in glob(path + '/*'):

print f.strip()

@printSeparator

def traverseDirByListdir(path):

path = os.path.expanduser(path)

for f in os.listdir(path):

print f.strip()

@printSeparator

def traverseDirByOSWalk(path):

path = os.path.expanduser(path)

for (dirname, subdir, subfile) in os.walk(path):

#print('dirname is %s, subdir is %s, subfile is %s' % (dirname, subdir, subfile))

print('[' + dirname + ']')

for f in subfile:

print(os.path.join(dirname, f))

if __name__ == '__main__':

path = r'~/src/py'

traverseDirByGlob(path)

traverseDirByGlob(path)

traverseDirByListdir(path)

traverseDirByOSWalk(path)
