如何从 beautifulsoup 数据写入 csv

Question

希望将我用 beautifulsoup 提取的数据转换为 .csv 文件

这是要提取的代码：

from requests import get

url = 'https://howlongtobeat.com/game.php?id=38050'

    response = get(url)

    from bs4 import BeautifulSoup

    html_soup = BeautifulSoup(response.text, 'html.parser')

    game_name = html_soup.select('div.profile_header')[0].text
    game_length = html_soup.select('div.game_times li div')[-1].text
    game_developer = html_soup.find_all('strong', string='\nDeveloper:\n')[0].next_sibling
    game_publisher = html_soup.find_all('strong', string='\nPublisher:\n')[0].next_sibling
    game_console = html_soup.find_all('strong', string='\nPlayable On:\n')[0].next_sibling
    game_genres = html_soup.find_all('strong', string='\nGenres:\n')[0].next_sibling

我想将这些结果写入 csv（它正在提取我想要的信息，但我认为它需要清理）

不确定如何写入 csv 或清理数据

请帮忙

Answer 1

你可以使用csv.writer:

import csv, re
from bs4 import BeautifulSoup as soup
import requests
flag = False
with open('filename.csv', 'w') as f:
  write = csv.writer(f)
  for i in range(1, 30871):
    s = soup(requests.get(f'https://howlongtobeat.com/game.php?id={i}').text, 'html.parser')
    if not flag: #write header to file once
      write.writerow(['Name', 'Length']+[re.sub('[:\n]+', '', i.find('strong').text) for i in s.find_all('div', {'class':'profile_info'})])
      flag = True
    name = s.find('div', {"class":'profile_header shadow_text'}).text
    length = [[i.find('h5').text, i.find("div").text] for i in s.find_all('li', {'class':'time_100'})]
    stats = [re.sub('\n+[\w\s]+:\n+', '', i.text) for i in s.find_all('div', {'class':'profile_info'})]
    write.writerows([[name, length[0][-1]]+stats[:4]])

您可以使用 Python 的 csv 模块：https://docs.python.org/3/library/csv.html 或 https://docs.python.org/2.7/library/csv.html。

为了将此数据写入 CSV 文件，

game_info = [game_name, game_publisher, game_console, game_genre, game_length, game_developer]
with open("game.csv", 'w') as outfile:
    csv.register_dialect('custom', delimiter='\n', quoting=csv.QUOTE_NONE, escapechar='\\')
    writer = csv.writer(outfile,'custom')
    row = game_info
    writer.writerow(row)
