I am writing a program to crawl images from a website and it shows the list of images present in the website. The user can select which images to save from the given list. If I try to download all the images, there is no problem. But, when I select some images and try to download it, it cannot be viewed.

def fetch_url():

    url = _url.get()

    config['images'] = 

    _images.set(())



    try:

        page = requests.get(url)

    except requests.RequestException as rex:

        _sb(str(rex))

    else:

        soup = BeautifulSoup(page.content, 'html.parser')

        images = fetch_images(soup, url)

        if images:

            _images.set(tuple(img['name'] for img in images))

            _sb('Images found: {}'.format(len(images)))

        else:

            _sb('No images found!.')

        config['images'] = images





def fetch_images(soup, base_url):

    images = 

    for img in soup.findAll('img'):

       src = img.get('src')

       img_url = ('{base_url}/{src}'.format(base_url=base_url, src=src))

       name = img_url.split('/')[-1]

       if name[-3:] == "png" or name[-3:] == "jpg" or name[-4:] == "jpeg": ### <- here

           images.append(dict(name=name, url=img_url))

    return images





def fetch_selected_images(event):

    widget = event.widget

    selected_idx = widget.curselection()

    selected_items = [widget.get(int(item)) for item in selected_idx]

    selected_images = 

    url = _url.get() + '/img'



    for img in selected_items:

        img_url = ('{base_url}/{src}'.format(base_url=url, src=img))

        name = img_url.split('/')[-1]

        if name in selected_items:

            selected_images.append(dict(name=name, url=img_url))

        for idx in selected_idx:

            widget.itemconfig(idx, fg='red')



    config['images'] = selected_images
