Thanks the help of this forum, i'm finally arrived at this python3 code:
import urllib.request
from bs4 import BeautifulSoup
url= 'https://www.inforge.net/xi/forums/liste-proxy.1118/'
soup = BeautifulSoup(urllib.request.urlopen(url), "lxml")
for tag in soup.find_all('a', {'class':'PreviewTooltip'}):
links = (tag.get('href'))
print (links)
It prints all the links of topics in the webpage: https://www.inforge.net/xi/forums/liste-proxy.1118/ But the last thing that I need is: how to tell python to write ad every line, first the "threads" word, the other part of the link? (https://www.inforge.net/xi/) Thanks in advance!
