我只想打印來自 GoogleNews 的 1 個故事

Question

我目前正試圖弄清楚如何從 GoogleNews 打印 1 個單一的故事，現在我還不得不提到我正在抓取它，這使得它變得更加困難（我猜）。 我也嘗試用谷歌搜索它，但我在互聯網上找不到任何東西。 所以這是我的代碼：

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)

所以當我運行這段代碼時，它會返回一堆今天的故事，但我只想打印出 1. 故事。 有沒有辦法做到這一點？

Answer 1

您可以使用 find 方法來做到這一點，如下所示：

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)

輸出：
