利用Python对文件夹下图片数据进行批量改名的代码实例

# -*- coding:utf8 -*-import osclass BatchRename():  '''  批量重命名文件夹中的图片文件  '''  def __init__(self):    self.path = 'C:/Users/ThinkPad User/Desktop/weibo'  def rename(self):    filelist = os.listdir(self.path)    total_num = len(filelist)    i = 0    for item in filelist:      if item.endswith('.jpg'):        src = os.path.join(os.path.abspath(self.path), item)        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)if __name__ == '__main__':  demo = BatchRename()  demo.rename()
