python实现对文件中图片生成带标签的txt文件方法

import os
def generate(dir,label):
  files = os.listdir(dir)
  files.sort()
  print '****************'
  print 'input :',dir
  print 'start...'
  listText = open(dir+'\\'+'list.txt','w')
  for file in files:
    fileType = os.path.split(file)
    if fileType[1] == '.txt':
      continue    
    name = file + ' ' + str(int(label)) +'\n'
    listText.write(name)
  listText.close()
  print 'down!'
  print '****************'  

if __name__ == '__main__': 
  generate('C:\\Users\\Desktop\\image',1)
