Web Python mengikis banyak halaman

Question

Saya mengorek semua kata dari situs web Merriam-Webster .

Saya ingin mengikis semua halaman mulai dari az dan semua halaman di dalamnya dan menyimpannya ke file teks. Masalah yang saya alami adalah saya hanya mendapatkan hasil pertama dari tabel, bukan semua. Saya tahu bahwa ini adalah teks dalam jumlah besar (sekitar 500k) tetapi saya melakukannya untuk mendidik diri saya sendiri.

KODE:

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)

Sekarang yang saya inginkan adalah mendapatkan semua entri dari tabel ini, tetapi saya hanya mendapatkan entri pertama.

Saya agak terjebak di sini jadi bantuan apa pun akan dihargai. Terima kasih

Answer 1

Untuk mendapatkan semua entri, Anda dapat menggunakan contoh ini:

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']))

Untuk mengikis banyak halaman:

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: Untuk mendapatkan semua halaman dari A hingga 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: Untuk menyimpan ke file:

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

Saya pikir Anda membutuhkan loop lain:

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