Hello,

Here is simple code that get error:

from urllib.request import urlopen
from bs4 import BeautifulSoup

url = 'https://www.amazon.com/Advanced-ASP-NET-Core-Security-Vulnerabilities/dp/1484260139/ref=sr_1_1?dchild=1&keywords=Advanced+ASP.NET+Core+3+Security&qid=1602852997&s=books&sr=1-1.html'

html = urlopen(url)

============ RESTART: /home/pavel/python_code/parse_amazon_url.py ============
Traceback (most recent call last):
File "/home/pavel/python_code/parse_amazon_url.py", line 6, in <module>
html = urlopen(url)

Where is a problem ?

Thanks

You're going to need to post the entire traceback as the piece you've shown doesn't say what the problem is.

Use Requests and not urllib,also need a user agent to not get 503.
Will also need Selenium as Amazon(use a lot of JavaScript).

To show a demo with Requests.

import requests
from bs4 import BeautifulSoup

url = 'https://www.amazon.com/Advanced-ASP-NET-Core-Security-Vulnerabilities/dp/1484260139/ref=sr_1_1?dchild=1&keywords=Advanced'
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36'}
response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.content, 'lxml')
print(soup.find('title').text)

Test:

Output:
Amazon.com
>>> response
<Response [200]>
>>> soup.p
<p class="a-last">Sorry, we just need to make sure you're not a robot. For best results, please make sure your browser is accepting cookies.</p>

So now get 200,but as you see now need browser and cooike.
This is when Selenium come into the picture,search the forum for this can also look at web-scraping part-2.

You can also send cookies with requests. That being said, Selenium may well be the best option.

If you haven't used html_requests, i would recommend looking at that for anything javascript related. Its a great tool and is an in-between with selenium and requests
