我目前正試圖弄清楚如何從 GoogleNews 列印 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，它會回傳一堆今天的故事，但我只想列印出 1. 故事。有沒有辦法做到這一點？
uj5u.com熱心網友回復：
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)
或者您可以使用串列切片：
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)
