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：
importos
defanyTrue(predicate,sequence):
returnTrueinmap(predicate,sequence)
deffilterFiles(folder,exts):
forfileNameinos.listdir(folder):
ifos.path.isdir(folder+'/'+fileName):
filterFiles(folder+'/'+fileName,exts)
elifanyTrue(fileName.endswith,exts):
printfileName
exts=['.md','.yml','.rst']
filterFiles('D:\\Twisted\\twisted-trunk',exts)
importos

filterFiles('D:\\Twisted\\twisted-trunk',exts)
print('totaltime=%f'%(time.time()-start))
