1.os.popen運(yùn)行shell列表命令
代碼如下:
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.
代碼如下:
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
代碼如下:
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(xiàng)目的元組:當(dāng)前目錄名稱,子目錄名稱,子文件名稱
代碼如下:
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:
代碼如下:
#!/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))
