使用 BeautifulSoup 抓取 url

Question

Hello I am beginner in data scraping. At this case I want to get an url like "https:// . . ." but the result is a list in link variable that contain of all links in web. Here the code below;

import requests
from bs4 import BeautifulSoup
url = 'https://www.detik.com/search/searchall?query=KPK'
page = requests.get(url)
soup = BeautifulSoup(page.content, 'html.parser')
artikel = soup.findAll('div', {'class' : 'list media_rows list-berita'})
p = 1
link = []
for p in artikel:
     s = p.findAll('a', href=True)['href']
     link.append(s)

the result of the code above is getting error such as

TypeError                                 Traceback (most recent call last)
<ipython-input-141-469cb6eabf70> in <module>
3 link = []
4 for p in artikel:
5         s = p.findAll('a', href=True)['href']
6         link.append(s)
TypeError: list indices must be integers or slices, not str

The result is I want to get all links of https:// . . . in <div class = 'list media_rows list-berita' as a list Thank you in advance.

Code:

import requests
from bs4 import BeautifulSoup

url = 'https://www.detik.com/search/searchall?query=KPK'
page = requests.get(url)
soup = BeautifulSoup(page.content, 'html.parser')
articles = soup.findAll('div', {'class' : 'list media_rows list-berita'})
links = []

for article in articles:
    
    hrefs = article.find_all('a', href=True)
    for href in hrefs:
        links.append(href['href'])
        
print(links)

Output:

Answer 2

There is only one div with the class list media_rows list-berita . So you can use find instead of findAll

1. Select the div with class name list media_rows list-berita
2. Select all the <a> with findAll from the div . This will give you a list of all <a> tags present inside the div
3. Iterate over all the <a> from the above list and extract the href .

Here is a working code.

import requests
from bs4 import BeautifulSoup
url = 'https://www.detik.com/search/searchall?query=KPK'
page = requests.get(url)
soup = BeautifulSoup(page.content, 'html.parser')
artikel = soup.find('div', {'class' : 'list media_rows list-berita'})
a_hrefs = artikel.findAll('a')
link = []
for k in a_hrefs:
     link.append(k['href'])

print(link)
