我想使用网站上的python解析来自多个json+id标记的数据

Question

我在找能帮我的人。我想解析来自JSON+ID标记的数据。在这个网站上，有3个不同的JSON+ID标记，我想从第一个标记中获取数据。但它会自动解析我不需要的第二个标记的数据。有一个链接https://www.wayfair.com/home-improvement/pdp/orren-ellis-lina-36-single-bathroom-vanity-set-oris2048.html

这是我的密码

import requests as re
from bs4 import BeautifulSoup as bs
import json
import csv


source=re.get("https://www.wayfair.com/home-improvement/pdp/orren-ellis-lina-36-single-bathroom-vanity-set-oris2048.html")
parse=bs(source.text,'html.parser')
js = json.loads(parse.find("script",type="application/ld+json").text)
print(js)

它只给我这个输出

<script type="application/ld+json">{"@context":"http://schema.org","@type":"WebSite","name":"Wayfair","url":"https://www.wayfair.com"}</script>

但是我想要这个标记json+id标记数据，而不是另一个

Have to do some more work on the bathroom, including the wall (so don't mind the mess)--so it can hang evenly, and then we'll fully attach the sink, that's why there looks like there is a gap between the cabinets and sink top, in case you notice.
