The link is redirecting me to an archives page with other top stories https://www.coindesk.com/news/babel-finance-bets-on-longtime-fintech-hand-to-help-navigate-regulatory-landscape. The tag news on the link between .com and babel should not be there as I believe it is that which is redirecting the news headline to another page.
from bs4 import BeautifulSoup
import requests
base_url ='https://www.coindesk.com/news'
source = requests.get(base_url).text
soup = BeautifulSoup(source, "html.parser")
articles = soup.find_all(class_ = 'list-item-card post')
#print(len(articles))
#print(articles)
for article in articles:
headline = article.h4.text.strip()
link = base_url + article.find_all("a")[1]["href"]
text = article.find(class_="card-text").text.strip()
img_url = base_url+article.picture.img['src']
print(headline)
print(link)
print(text)
print("Image " + img_url)
```
The error happens because you are concatinating your base link (which already includes /news/) to an absolute url
To prevent this, you can use urllib.parse.urljoin()
In your example this should fix the issue:
from urllib.parse import urljoin
link = urljoin(base_url, article.find_all("a")[1]["href"])
