用蟒蛇美丽的汤刮网的空值
提问于 2018-03-09 10:43:35
我试图取消这个网站，但有问题，提取正确的价值观。该网站是关于银，黄金，钯和铂的价格。http://www.lbma.org.uk/precious-metal-prices网站的html在下面。
<div id="header-tabs-content" data-tabs-content="header-tabs">
<div class="tabs-panel is-active" id="header-tabs-panel1"
role="tabpanel" aria-hidden="false" aria-labelledby="header-tabs-
panel1-label">
<a href="/precious-metal-prices">
<p>Gold Price</p>
<p>AM:
<strong>$
<span id="daily_gold_am_usd">1325.40</span>
</strong> <br>
<em class="update">Updated: <span
id="daily_gold_am_timestamp">08/03 10:31:00</span></em> </p>
<p>PM:
<strong>$
<span id="daily_gold_pm_usd">1321.00</span>
</strong> <br>
<em class="update">Updated: <span
id="daily_gold_pm_timestamp">08/03 15:02:00</span></em> </p>
</a>我有兴趣从下面的html数据结构中获得1325.40的daily_gold_am_usd和1321.00的daily_gold_pm_usd。但是，我在查阅过去文章后尝试的代码似乎无法返回这些值。
#Import packages
import pandas as pd
import numpy as np
import requests
from bs4 import BeautifulSoup
#define url and get html
url = "http://www.lbma.org.uk/precious-metal-prices"
r=requests.get(url)
data=r.text
soup = BeautifulSoup(data,"html.parser")
#Find the object of interest
gold_am_price = soup.find("span", {"id": "daily_gold_am_usd"})
Au_price_am = gold_am_price.text.strip()
gold_pm_price = soup.find("span", {"id": "daily_gold_pm_usd"})
Au_price_pm = gold_pm_price.text.strip()感谢你的帮助。谢谢你们。

这些值来自XHR到http://lbma.oblive.co.uk/api/today/both.json，因此您可以将它们作为：
import requests
url = "http://lbma.oblive.co.uk/api/today/both.json"
response = requests.get(url).json()print(response)输出
{'gold': {'am': {'usd': '1325.40', 'gbp': '955.080', 'eur': '1070.390', 'timesta
mp': '08/03 10:31:00'}, 'pm': {'usd': '1321.00', 'gbp': '953.370', 'eur': '1069.
750', 'timestamp': '08/03 15:02:00'}}, 'silver': {'usd': '16.48000', 'usdc': '16
48', 'gbp': '11.89000', 'gbpp': '1189', 'eur': '13.31000', 'eurc': '1331', 'time
stamp': '08/03 12:01:00'}, 'platinum': {'am': {'usd': '949.00', 'gbp': '683.960'
, 'eur': '766.250', 'timestamp': '08/03 09:49:00'}, 'pm': {'usd': '954.00', 'gbp
': '687.570', 'eur': '769.670', 'timestamp': '08/03 14:09:00'}}, 'palladium': {'
am': {'usd': '970.00', 'gbp': '699.100', 'eur': '783.210', 'timestamp': '08/03 0

p': '08/03 14:09:00'}}}然后，您可以提取所需的内容如下：
response['gold']['am']['usd'] # 1325.40
response['gold']['pm']['usd'] # 1321.00页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
