Learning about web scraping, having issues with my scraper: I am currently following a tutorial and writing it in py 3 using jupiter. I have no idea as to what the printed error means? Any suggestions?

(My scrape code)

import urllib.request
from bs4 import BeautifulSoup
url = “https://old.reddit.com/top/”

download the URL and extract the content to the variable html

request = urllib.request.Request(url)
html = urllib.request.urlopen(request).read()

pass the HTML to Beautifulsoup.

soup = BeautifulSoup(html,‘html.parer’)

get the HTML of the table called site Table where all the links are displayed

main_table = soup.find(“div”,attrs={‘id’:‘siteTable’})

Now we go into main_table and get every a element in it which has a class “title”

links = main_table.find_all(“a”,class_=“title”)

from each link extract the text of link and the link itself

List to store a dict of the data we extracted

extracted_records = []
for link in links:
title = link.textT
url = link[‘href’]
record = {
‘title’:title,
‘url’:url
}
extracted_records.append(record)
print(extracted_records)

(The return)

HTTPError Traceback (most recent call last)
