我想从包含多个标签(和字符串)的多个项目的列表中提取特定的字符串。并将它们存储到变量中。
from bs4 import BeautifulSoup
from requests_html import HTMLSession
session = HTMLSession()
r = session.get('https://www.khanacademy.org/profile/DFletcher1990/')
r.html.render(sleep=5)
soup=BeautifulSoup(r.html.html,'html.parser')
user_socio_table=soup.find_all('div', class_='discussion-stat')
print(user_socio_table)
以下是print(user_socio_table)
的假定输出:
[<div class="discussion-stat">
4<span class="discussion-light"> questions</span>
</div>, <div class="discussion-stat">
444<span class="discussion-light"> votes</span>
</div>, <div class="discussion-stat">
718<span class="discussion-light"> answers</span>
</div>, <div class="discussion-stat">
15<span class="discussion-light"> flags raised</span>
</div>, <div class="discussion-stat">
10<span class="discussion-light"> project help requests</span>
</div>, <div class="discussion-stat">
38<span class="discussion-light"> project help replies</span>
</div>, <div class="discussion-stat">
208<span class="discussion-light"> comments</span>
</div>, <div class="discussion-stat">
11<span class="discussion-light"> tips and thanks</span>
</div>]

您可以将值一一添加到json数组中
data = {}
for gettext in user_socio_table:
category = gettext.find('span')
category_text = category.text.strip() ## get text in span
number = category.previousSibling.strip() ## get value before span tag
data[category_text] = number ## add it
print(data)
输出:
{'questions': '4', 'votes': '444', 'answers': '718', 'flags raised': '15', 'project help requests': '10', 'project help replies': '38', 'comments': '208', 'tips and thanks': '11'}
您可以通过专业的方式获得价值
print(data['questions'])
输出:
4
