python实现查找指定文件

若不包含子目录的遍历：

 

import glob

 

for filename in glob.glob("/data/testdata/*.jpg"):

    print filename

 

 

包含子目录

 

import os

import fnmatch

 

def iterfindfiles(path, fnexp):

    for root, dirs, files in os.walk(path):

        for filename in fnmatch.filter(files, fnexp):

            yield os.path.join(root, filename)

 

for filename in iterfindfiles(r"/data/testdata", "*.jpg"):

    print filename
