Iのリンク文書に書かれています。
III.Beautifulsoupでデータを取得
1.BBCのトップページを読み込む
# import libraries
import requests
from bs4 import BeautifulSoup as bs
# read the page and parse it
page = requests.get('https://www.bbc.com/news')
soup = bs(page.content, 'html.parser')2.Most watchedとMost readのHTMLのclass=を見つける
Most watachedは５件、Most readは１０件です。
次はBrave BrowserのView>Developer>Inspect Elementsの画面です。ブラウザによってはDeveloperを表示するよう設定する必要があります。
ポインターをおくとハイライトされます（Command+Shift+C）。
次からタイトルの書かれているclassは、“gs-c-promo-heading__title gel-pica-bold”であることがわかります。
<span class="gs-c-promo-heading__title gel-pica-bold">Homes and buildings destroyed in Israel and Gaza</span>
3.テキストを含むclassを取得
top5_10 = [heading for heading in soup.find_all(class_= "gs-c-promo-heading__title gel-pica-bold")]
top5_10## [<span class="gs-c-promo-heading__title gel-pica-bold">The cost of calling out a 'rape joke'</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Homes and buildings destroyed in Israel and Gaza</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Netanyahu defends press building bombing</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Lebanon: A country in free-fall</span>, <span class="gs-c-promo-heading__title gel-pica-bold">One-minute World News</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Gaza says Sunday was 'deadliest day' so far</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Why is Gaza blurry on Google Maps?</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Hugs and holidays resume as rules ease for millions</span>, <span class="gs-c-promo-heading__title gel-pica-bold">India's Covid crisis hits vaccine-sharing scheme</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Taiwan orders toughest curbs amid Covid spike</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Four arrested in anti-Semitism video investigation</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Missing Houston tiger handed into police</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Tom Cruise signs shirts for Covid-hit football club</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Two killed in collapse at West Bank synagogue</span>, <span class="gs-c-promo-heading__title gel-pica-bold">Netanyahu says Gaza strikes to continue 'at force'</span>]4.テキストを取得

Googleシートにペーストして、次のコードで翻訳しました。
=googletranslate(セルの位置,"en","ja")
ちょっと訳がよくないですが、簡単なので大目にみましょう。がんばれば、Google翻訳を利用したトップニュース翻訳アプリも作れそうですが、、、相当な頑張りが必要かも。
