How to set name for download images_问答_开发者

I think I need help with for loop. I have a list of 33 images. For each image I need to create a name: name, reference and number. Every product with the same reference number has to ends with number from 1 to ...x

How to set name for download images

Can someone give me a hint how to finish the code? Now the products with same reference number are overwritten in the output (filenames).

import requests
from bs4 import BeautifulSoup


productlinks = []

for x in range(1, 2):
    r = requests.get(
        f'https://www.roco.cc/ren/products/locomotives/steam-locomotives.html?p={x}&verfuegbarkeit_status=41%2C42%2C43%2C45%2C44')
    soup = BeautifulSoup(r.content, 'lxml')
    productlist = soup.find_all('li', class_='item product product-item')

    for item in productlist:
        for link in item.find_all('a', class_='product-item-link', href=True):
            productlinks.append(link['href'])


wayslist = []

for url in productlinks :
   r = requests.get(url, allow_redirects=False)
   soup = BeautifulSoup(r.content, 'html.parser')
   images = soup.findAll('img')
   for image in images:
      if 'def' in image['src']:

        name = 'Roco'

        try:
            reference = soup.find(
                'span', class_='product-head-artNr').get_text().strip()
        except Exception as e:
            print(link)

        ways = image['src']
        
        wayslist.append(ways)

        with open(name + '_' + reference + '_' + '.jpg', 'wb') as f:
                im = reque开发者_如何学Csts.get(ways)
                f.write(im.content)
                print('Writing: ', ways)
        
       
print(len(wayslist))

You can use enumerate:

images = soup.findAll('img')

for i, image in enumerate(images):
    if 'def' in image['src']:

    name = 'Roco'

    try:
        reference = soup.find(
            'span', class_='product-head-artNr').get_text().strip()
    except Exception as e:
        print(link)

    ways = image['src']
    
    wayslist.append(ways)

    with open(name + '_' + reference + '_' + str(i + 1) + '.jpg', 'wb') as f:
        im = requests.get(ways)
        f.write(im.content)
        print('Writing: ', ways)

In the output all files starts with number 4 (the end of name before .jpg)
