使用python bs4时如何从嵌套标签中获取信息？

要获得“星星”，您可以使用该.get_text()方法。要获取“存储库”，您可以使用该next_sibling方法

在这个例子中，我已经介绍了如何获取所有信息，包括“存储库”、“星星”和开发人员名称（“内置购买”）。

import requests
from bs4 import BeautifulSoup


url_github = "https://github.com/trending"


def request_github_trending(url):
    request = requests.get(url)
    return request


def extract(page):
    soup = BeautifulSoup(page.content, "html.parser")
    return soup.find_all("article", class_="Box-row")


def print_info(html):
    fmt_string = "{:<60} {:<30} {}"
    print(fmt_string.format("Repo", "Stars", "Built by"))
    print("-" * 150)
    for tag in html:
        repository_info = tag.find(class_="text-normal")
        repository = repository_info.text.strip() + repository_info.next_sibling.strip()

        stars = tag.find(class_="Link--muted d-inline-block mr-3").get_text(strip=True)

        usernames = [user["alt"] for user in tag.find_all("img")]
        print(fmt_string.format(repository, stars, usernames))


print_info(extract(request_github_trending(url_github)))

输出：

Repo                                                         Stars                          Built by
