将相同后缀的图片文件改成有序图

【作用】将以相同后缀（.PNG,.JPG,…）的图片文件改成有序图。
【代码】
使用方法：只需要更改selfpath路径，改成需要变动的文件夹名称。

# -*- coding:utf-8 -*-

import os

class ImageRename():
    def __init__(self):
        #这句代码没有作用
        self.path = 'G:\Data\times_square'

    def rename(self):
        # F:\PotPlayer\PotPlayerInstall\PotPlayer\Capture
        selfpath='F:\\PotPlayer\\PotPlayerInstall\\PotPlayer\\Capture'
        filelist = os.listdir(selfpath)
        total_num = len(filelist)
        i = 0
        for item in filelist:
            print(item)
            if item.endswith('.jpg'):
                src = os.path.join(os.path.abspath(selfpath), item)
                dst = os.path.join(os.path.abspath(selfpath), 'image' + str(i) + '.jpg')
                os.rename(src, dst)
                print('converting %s to %s ...' % (src, dst))
                i = i + 1
           #  print 'total %d to rename & converted %d jpgs' % (total_num, i)

if __name__ == '__main__':
    newname = ImageRename()
    newname.rename()

【结果】
