Python для цикла внутри цикла for

Вы можете использовать findAll вместо find, чтобы получить все имена, а затем использовать переменную, чтобы отслеживать, какое имя pdf следует использовать.

for url in productlinks:
    r = requests.get(url, allow_redirects=False)
    soup = BeautifulSoup(r.content, 'html.parser')
    # set variable to 0
    num_of_pdfs = 0
    for tag in soup.find_all('a'):
        on_click = tag.get('onclick')
        if on_click:
            pdf = re.findall(r"'([^']*)'", on_click)[0]

            if 'pdf' in pdf:
                name = 'Roco'

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

            try:
                # use find all and use the current pdf as index
                pdfname = soup.findAll('td', class_='col-download-data')[num_of_pdfs].get_text().strip()
                # increment num_of_pdfs to get the next name on next iteration
                num_of_pdfs += 1
            except Exception as e:
                print(e)

            print(name, reference, pdfname)

Замените это

    try:
        pdfname = soup.find('td', class_='col-download-data').get_text().strip()
    except Exception as e:
        print(e)

с этим:

        try:
            pdfname = ""
            for tag in soup.find_all('td',  class_='col-download-data'):
              pdfname = pdfname + "," + tag.get_text().strip()
            
        except Exception as e:
          print(e)

Спасибо за помощь, ребята. Закончил одну часть кода:

    try:
        os.mkdir(os.path.join(os.getcwd(), pdffolder))
    except:
        pass
    os.chdir(os.path.join(os.getcwd(), pdffolder))

    for url in productlinks:
        r = requests.get(url, allow_redirects=False)
        soup = BeautifulSoup(r.content, 'html.parser')
        num_of_pdfs = 0
        for tag in soup.find_all('a'):
            on_click = tag.get('onclick')
            if on_click:
                pdf = re.findall(r"'([^']*)'", on_click)[0]
                if 'pdf' in pdf:

                    name = 'Roco'

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

                try:
                    pdfname = soup.findAll(
                        'td', class_='col-download-data')[num_of_pdfs].get_text().strip().lower()
                    pdfname = pdfname.replace(' ', '_')
                    num_of_pdfs += 1
                except Exception as e:
                    print(e)

                pdflist.append(pdf)

                with open(name + '-' + reference + '-' + pdfname + '-' + '.pdf', 'wb') as f:
                    im = requests.get(pdf)
                    f.write(im.content)

                pdfs = {
                    'Manufacturer_name': name,
                    'Reference': reference,
                    'Documents': name + '_' + reference + '_' + pdfname + '.pdf'
                }

                doculist.append(pdfs)


pdfpath('Rocco - pdf')
