Getting 'list index out of range' while fetching product details using BeautifulSoup?

[PrateekG]

First Issue-

check_merchant_product_id = soup.find('div', attrs={'class': 'description'}).findAll('span')[3]
                if check_merchant_product_id is not None:
                    merchant_product_id = check_merchant_product_id.text
                if merchant_product_id is not None:
                    prod_details['merchant_product_id'] = merchant_product_id

Error:
getting 'Product Code:' instead of value

Second Issue-

prod_details['merchant_image_urls'] = ",".join(list(filter(None, map(lambda x: x['href'].replace(",", "%2C"),
                                                                                         soup.find('div', attrs={
                                                                                             'class': 'left'}).findAll(
                                                                                             'a')))))

Error:
getting broken image urls

Third Issue-

check_price = soup.find('span', attrs={"class": "price-old"})
                    if check_price is not None:
                        prod_details['price'] = check_price.text.replace("SGD $", "")
                    check_sale_price = soup.find('span', attrs={"class": "price-new"})
                    if check_sale_price is not None:
                        prod_details['sale_price'] = check_sale_price.text.replace("SGD $", "")

Error:
getting NaN for some products
