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))
