BeautifulSoup
from bs4 import BeautifulSoup

soup = BeautifulSoup(raw) #rawはwebページ読み込みデータ

#findAll:該当するタグのオブジェクトをリストで取得
#下記だとクラスがimage-itemsのulを全取得
ul_items = soup.findAll('ul',class_='image-items')

#find:該当するタグのオブジェクトを1件取得
a = item.find('a')
#id指定だとこんな感じ
sample = soup.find(id='template-embed-sample')

#属性値の取得
#aタグのリンク先の取得
link = a.attrs['href']

findメソッドで得たBeautifulSoupオブジェクト?は内包している子の情報をもつので
下記のような取得もできる

<div><span>hogehoge</span><div>

hogehogeを取得するのに

div = soup.find('div')
span = div.find('span')#div内のspanを探す
print(span.text)
