Python 将JPEG图片批量改成jpg并删除JPEG图片

import os
import glob
from PIL import Image

root_dir = './image_net_mini'
dirs = os.listdir(root_dir)
for path in dirs:
    JPEG_list = glob.glob(root_dir+'/'+path+'/*.JPEG')
    for jpeg in JPEG_list:
        img = Image.open(jpeg)
        new_path = jpeg.replace('.JPEG', '.jpg')
        # print(img.filename)
        img.save(new_path, "JPEG", quality=80, optimize=True, progressive=True)
        os.remove(jpeg)
