Python3与Bs4的刮削

我正在尝试使用Python3（使用PyCharm）刮取这个网站的HTML。 我只对房子的价格感兴趣，因此我将搜索范围缩小到某些跨度，如：

import requests
from bs4 import BeautifulSoup


page = requests.get('https://www.idealista.com/venta-viviendas/madrid-madrid/')

soup = BeautifulSoup(page.text, 'html.parser')


prices=soup.findAll("span", {"class": "item-price h2-simulated"})

print(len(prices))
print(prices)

当我运行它时，我得到以下信息：0 []

---

这意味着它什么也找不到。此外，如果我打印所有内容：打印（soup）那么大的页面，我得到的html内容很少，因此它显然不能获取所有内容。

该网站是动态的，因此，您需要使用浏览器操作工具，例如：

输出：

你可以在头等舱找到，我也认为这是找到所有
