Question

I need help to upload mutiple images in firebase

        cloud_img = "images/example" + str(random.randint(1, 18596)) 
        storage.child(cloud_img).put(files, user['idToken'])
        imgurl = storage.child(cloud_img).get_url(user['idToken'])


        def Convert(string): 
            li = list(string.split(",")) 
            return li 
        urllist = imgurl
        # print(Convert(urllist))
        x = Convert(urllist)


        data = {
        "name": name,
