python批量更改图片名

• 将路径改为图片所在的父文件夹

# import os
#
# path = r"F:\imagenet\class1"
# fileList = os.listdir(path)
# os.chdir(path)
# l = len(fileList)
# i = 1
# for item in fileList:
#     if item.endswith('.jpg'):
#         os.rename(item, ('img' + str(i) + '.jpg'))
#     i = i + 1
#
# print("{}张图片转换成功->{}".format(l, i))

import os
import re


def replcaeFileName(pic_path):  # 修改pic_path路径下的文件名
   piclist = os.listdir(pic_path)
   total_num = len(piclist)
   i = 1
   for pic in piclist:
       if pic.endswith(".jpg"):  # 修改成你自己想要重命名的文件格式
           old_path = os.path.join(os.path.abspath(pic_path), pic)
           new_path = os.path.join(os.path.abspath(pic_path), 'img' + str((int(i))) + '.jpg')

           os.renames(old_path, new_path)
           print("把原图片命名格式：" + old_path + u"转换为新图片命名格式：" + new_path)
           i = i + 1
   print("总的图片数:{}".format(total_num))

if __name__ == '__main__':
   rootDir = 'F:/imagenet/train/class5'
   replcaeFileName(rootDir)
