nonetype object 抓取数据时没有属性文本错误

Question

when i try to scrap data from this amazon link . I got AttributeError: 'NoneType' object has no attribute 'text'

My Code:

headers = ({'User-Agent' : 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:103.0) Gecko/20100101 Firefox/103.0',
       'Accept-Language' : 'en-US,en;q=0.5'})
lap_site = requests.get('https://www.amazon.in/s?k=laptops&sprefix=%2Caps%2C634&ref=nb_sb_ss_recent_3_0_recent',headers = headers)
lap_soup = bs(lap_site.content,'lxml')
content = lap_soup.find('div',class_ = 's-desktop-width-max s-desktop-content s-opposite-dir sg-row')
lap_detail_block = content.find_all('div',class_ = 'a-section a-spacing-small a-spacing-top-small')
lap_name = lap_price = lap_rating = []
for i in lap_detail_block:

   laptop_name = i.find('h2').a.span.text
   lap_name.append(laptop_name)

   laptop_rating = i.find('span',class_ = 'a-icon-alt').text
   lap_rating.append(laptop_rating)

   laptop_price = i.find('span',class_ = 'a-price-whole').text   
   lap_price.append(laptop_price)

laptop_details = {
'Laptop':lap_name,
'Price':lap_price,
'Rating':lap_rating }

print(laptop_details)

I think that the laptop_rating variable store the content in string format even if we not include .text . I'm thinking that might be the reason for getting NoneType error, as we are extracting text from text. Anyway that's not the issue. How to extract the price or rating from that link?

At least from my tests, that page is recognizing automated access and blocks it. You need to use something like cloudscraper to do it. The following code will return the expected results (adapt to your own circumstances):

import cloudscraper
import pandas as pd
from bs4 import BeautifulSoup

scraper = cloudscraper.create_scraper()

r = scraper.get('https://www.amazon.in/s?k=laptops&sprefix=%2Caps%2C634&ref=nb_sb_ss_recent_3_0_recent')
soup = BeautifulSoup(r.content, 'html.parser')
# print(soup)
content = soup.find('div',class_ = 's-desktop-width-max s-desktop-content s-opposite-dir sg-row')
lap_detail_block = content.find_all('div',class_ = 'a-section a-spacing-small a-spacing-top-small')
lap_name = lap_price = lap_rating = []
for i in lap_detail_block:
    try:
       laptop_name = i.find('h2').a.span.text
       lap_name.append(laptop_name)

       laptop_rating = i.find('span',class_ = 'a-icon-alt').text
       lap_rating.append(laptop_rating)

       laptop_price = i.find('span',class_ = 'a-price-whole').text   
       lap_price.append(laptop_price)

       laptop_details = {
        'Laptop':lap_name,
        'Price':lap_price,
        'Rating':lap_rating 
       }
       print(laptop_name, laptop_rating, laptop_price)
    except Exception as e:
        print(e)
    print('_____________')

This will print out in terminal:
