Python批量重命名文件夹中图像文件的完整实现

import os

 def __init__(self):
  self.path = 'C:/Users/zxl/Desktop/tr'

 def rename(self):
  filelist = os.listdir(self.path)
  total_num = len(filelist)

    dst = os.path.join(os.path.abspath(self.path), str(i) + '.jpg')
    try:
     os.rename(src, dst)
     print 'converting %s to %s ...' % (src, dst)
     i = i + 1
    except:
     continue
  print 'total %d to rename & converted %d jpgs' % (total_num, i)
