Python Scraping:如何从具有Multiple的类中返回单个值

Question

我对使用Python很陌生。我正在丹麦一家股票交易网站上尝试使用BeautifulSoup来练习我的刮网技巧：https://www.nordnet.dk/markedet/aktiekurser

这是我的代码：

import requests
from bs4 import BeautifulSoup
page = requests.get('https://www.nordnet.dk/markedet/aktiekurser')
soup = BeautifulSoup(page.content, 'html.parser')
stocks = soup.find(id='tabs-tabpanel-0')
items = stocks.find_all(class_ ='c02356 c02375')
name = [item.find(class_ = 'c02393 c02394').get_text() for item in items]
Price = [item.find(class_ = 'number c02398').get_text() for item in items]
print(name)
print(Price)

它工作正常，但类"number c02398"似乎包含多个值，因为print(Price)返回两个值。如何更改代码，以便只从类中获得一个值？

Answer 1

这是在item变量中返回的span标记：

<span class="number c02398" style="white-space:nowrap"><span class="c02420"> <!-- -->426.2<!-- --> </span><span aria-hidden="true">426,20</span></span

1. 如果要获取aria-hidden属性为True的span标记内的值，请使用以下代码行：

Price = [item.find(class_ = 'number c02398').find("span", attrs={"aria-hidden":"true"}).get_text() for item in items]

2. 如果要获取类名为c02420的span标记内的值，请使用以下代码行：

Price = [item.find(class_ = 'number c02398').find("span").get_text() for item in items]
