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))
