So i am trying to scrape links from a random wikipedia page here is my code thus far:
from bs4 import BeautifulSoup
import requests
import pandas as pd
import urllib2
# function get random page
def get_random():
import requests
# r = requests.get('https://en.wikipedia.org/wiki/Special:Random')
r = requests.get('https://en.wikipedia.org/wiki/Carole_Ann')
return r.url
#========================
#finding the valid link
def validlink(href):
if href:
if re.compile('^/wiki/').search(href):
if not re.compile('/\w+:').search(href):
return True
return False
#validlink()===========
#the first site
a1 = get_random()
#print("the first site is: " + a1)
# the first site end()====
#looking for the article name:
blin = requests.get(a1)
soup = BeautifulSoup(blin.text, 'html.parser')
title = soup.find('h1', {'class' : 'firstHeading'})
print("starting website: " + a1 + " Titled: " + title.text)
print("")
#=============================
#first article done
#find body:
import re
body = requests.get(a1).text
soup = BeautifulSoup(body, 'lxml')
for link in soup.findAll("a"):
url = link.get("href", "")
print(
#======================
i know i'm doing this last part wrong. Im new to python so i just have no idea how to go about this part, what i need is to pull all of the links from a random site that the random page takes me to, then i pull the link and title off of that site, then i need to pull the wikipedia links off of that page which is what i am looking to do in that last bit of code there heres another snip:
and at this point i want to print all of the links that it finds after they have been tested against my valid links function at the top:
again forgive me for being new and not understanding at this. But please help i cannot figure this out.
so the question that i have is: i need to create a snippet of code that will pull out all of the website links off of the wikipedia page (which note i still dont know how to do the for loop was my best guess based on my own research) then i need to test the links that i pulled against my validlink function, and print out all of the valid links.
If you whan it as list then create new list and append()
url if it is valid.
Because the same url can be many times on page so I also check if url is already on list.
valid_urls = []
for link in soup.find_all('a'): # find_all('a', {'href': True}):
url = link.get('href', '')
if url not in valid_urls and validlink(url):
valid_urls.append(url)
print(valid_urls)
from bs4 import BeautifulSoup
import requests
import re
# --- functions ---
def is_valid(url):
"""finding the valid link"""
if url:
if url.startswith('/wiki/'): # you don't need `re` to check it
if not re.compile('/\w+:').search(url):
return True
return False
# --- main ---
#random_url = 'https://en.wikipedia.org/wiki/Special:Random'
random_url = 'https://en.wikipedia.org/wiki/Carole_Ann'
r = requests.get(random_url)
print('url:', r.url)
soup = BeautifulSoup(r.text, 'html.parser')
title = soup.find('h1', {'class': 'firstHeading'})
print('starting website:', r.url)
print('titled:', title.text)
print()
valid_urls = []
for link in soup.find_all('a'): # find_all('a', {'href': True}):
url = link.get('href', '')
if url not in valid_urls and is_valid(url):
valid_urls.append(url)
#print(valid_urls)
#for url in valid_urls:
# print(url)
print('\n'.join(valid_urls))
