Python web raspando várias páginas

Question

Estou copiando todas as palavras do site Merriam-Webster .

Quero raspar todas as páginas começando com az e todas as páginas dentro delas e salvá-las em um arquivo de texto. O problema que estou tendo é que só consigo o primeiro resultado da tabela, em vez de todos. Eu sei que esta é uma grande quantidade de texto (cerca de 500k), mas estou fazendo isso para me educar.

CÓDIGO:

import requests
from bs4 import BeautifulSoup as bs

URL = 'https://www.merriam-webster.com/browse/dictionary/a/'

page = 1
# for page in range(1, 75):

req = requests.get(URL + str(page))
soup = bs(req.text, 'html.parser')
containers = soup.find('div', attrs={'class', 'entries'})
table = containers.find_all('ul')

for entries in table:
    links = entries.find_all('a')
    name = links[0].text
    print(name)

Agora o que eu quero é obter todas as entradas desta tabela, mas em vez disso, obtenho apenas a primeira entrada.

Estou meio preso aqui, então qualquer ajuda seria apreciada. obrigado

Answer 1

Para obter todas as entradas, você pode usar este exemplo:

import requests
from bs4 import BeautifulSoup


url = 'https://www.merriam-webster.com/browse/dictionary/a/'
soup = BeautifulSoup(requests.get(url).content, 'html.parser')

for a in soup.select('.entries a'):
    print('{:<30} {}'.format(a.text, 'https://www.merriam-webster.com' + a['href']))

Impressões:

(a) heaven on earth            https://www.merriam-webster.com/dictionary/%28a%29%20heaven%20on%20earth
(a) method in/to one's madness https://www.merriam-webster.com/dictionary/%28a%29%20method%20in%2Fto%20one%27s%20madness
(a) penny for your thoughts    https://www.merriam-webster.com/dictionary/%28a%29%20penny%20for%20your%20thoughts
(a) quarter after              https://www.merriam-webster.com/dictionary/%28a%29%20quarter%20after
(a) quarter of                 https://www.merriam-webster.com/dictionary/%28a%29%20quarter%20of
(a) quarter past               https://www.merriam-webster.com/dictionary/%28a%29%20quarter%20past
(a) quarter to                 https://www.merriam-webster.com/dictionary/%28a%29%20quarter%20to
(all) by one's lonesome        https://www.merriam-webster.com/dictionary/%28all%29%20by%20one%27s%20lonesome
(all) choked up                https://www.merriam-webster.com/dictionary/%28all%29%20choked%20up
(all) for the best             https://www.merriam-webster.com/dictionary/%28all%29%20for%20the%20best
(all) in good time             https://www.merriam-webster.com/dictionary/%28all%29%20in%20good%20time

...and so on.

Para raspar várias páginas:

url = 'https://www.merriam-webster.com/browse/dictionary/a/{}'

for page in range(1, 76):
    soup = BeautifulSoup(requests.get(url.format(page)).content, 'html.parser')
    for a in soup.select('.entries a'):
        print('{:<30} {}'.format(a.text, 'https://www.merriam-webster.com' + a['href']))

---

EDIT: Para obter todas as páginas de A a Z:

import requests
from bs4 import BeautifulSoup


url = 'https://www.merriam-webster.com/browse/dictionary/{}/{}'

for char in range(ord('a'), ord('z')+1):
    page = 1
    while True:
        soup = BeautifulSoup(requests.get(url.format(chr(char), page)).content, 'html.parser')
        for a in soup.select('.entries a'):
            print('{:<30} {}'.format(a.text, 'https://www.merriam-webster.com' + a['href']))

        last_page = soup.select_one('[aria-label="Last"]')['data-page']
        if last_page == '':
            break

        page += 1

---

EDIT 2: Para salvar em arquivo:

import requests
from bs4 import BeautifulSoup


url = 'https://www.merriam-webster.com/browse/dictionary/{}/{}'


with open('data.txt', 'w') as f_out:
    for char in range(ord('a'), ord('z')+1):
        page = 1
        while True:
            soup = BeautifulSoup(requests.get(url.format(chr(char), page)).content, 'html.parser')
            for a in soup.select('.entries a'):
                print('{:<30} {}'.format(a.text, 'https://www.merriam-webster.com' + a['href']))

                print('{}\t{}'.format(a.text, 'https://www.merriam-webster.com' + a['href']), file=f_out)

            last_page = soup.select_one('[aria-label="Last"]')['data-page']
            if last_page == '':
                break

            page += 1

Answer 2

Acho que você precisa de outro loop:

for entries in table:
    links = entries.find_all('a')
    for name in links:
        print(name.text)
