我只想打印来自 GoogleNews 的 1 个故事

Question

我目前正在尝试弄清楚如何从 GoogleNews 打印 1 个故事，现在我还必须提到我正在 Web Scraping 它，这使得它变得更加困难（我猜）。我也尝试 google 它，但我在互联网上真的找不到任何东西。所以这是我的代码：

from bs4 import BeautifulSoup as soup
from urllib.request import urlopen

news_url = "https://news.google.com/rss?hl=de&gl=DE&ceid=DE:de"
Client = urlopen(news_url)
xml_page = Client.read()
Client.close()

soup_page = soup(xml_page, "xml")
news_list = soup_page.findAll("item")

for news in news_list:
    print(news.title.text)
    print(news.link.text)
    print(news.pubDate.text)

所以当我运行这段代码时，它 returns 今天的一堆故事，但我只想打印出 1. 故事。有什么办法吗？

Answer 1

您可以使用以下查找方法来完成此操作：

from bs4 import BeautifulSoup as soup
from urllib.request import urlopen

news_url = "https://news.google.com/rss?hl=de&gl=DE&ceid=DE:de"
Client = urlopen(news_url)
xml_page = Client.read()
Client.close()

soup_page = soup(xml_page, "xml")
news = soup_page.find("item")

#for news in news_list:
print(news.title.text)
print(news.link.text)
print(news.pubDate.text)

或者您可以使用列表切片：

from bs4 import BeautifulSoup as soup
from urllib.request import urlopen

news_url = "https://news.google.com/rss?hl=de&gl=DE&ceid=DE:de"
Client = urlopen(news_url)
xml_page = Client.read()
Client.close()

soup_page = soup(xml_page, "xml")
news_list = soup_page.findAll("item")

for news in news_list[:1]:
    print(news.title.text)
    print(news.link.text)
    print(news.pubDate.text)

输出：

Corona-News-Ticker: Die meisten Ungeimpften wollen ungeimpft bleiben - NDR.de
