python高效过滤出文件夹下指定文件名结尾的文件实例

如下所示:

import os

def anyTrue(predicate, sequence):

return True in map(predicate, sequence)

def filterFiles(folder, exts):

for fileName in os.listdir(folder):

if os.path.isdir(folder + '/' + fileName):

filterFiles(folder + '/' + fileName, exts)

elif anyTrue(fileName.endswith, exts):

print fileName

exts = ['.md', '.yml', '.rst']

filterFiles('D:\\Twisted\\twisted-trunk', exts)

import os

import time

from itertools import imap

def anyTrue(predicate, sequence):

return True in imap

(predicate, sequence)

def filterFiles(folder, exts):

for fileName in os.listdir(folder):

if os.path.isdir(folder + '/' + fileName):

filterFiles(folder + '/' + fileName, exts)

elif anyTrue(fileName.endswith, exts):

print fileName

start = time.time()

exts = ['.md', '.yml', '.rst']

filterFiles('D:\\Twisted\\twisted-trunk', exts)

print('total time=%f' %(time.time()- start))
