Python 3.x 在python中，如何从随下拉列表变化而变化的HTML中提取数据

我有一页

我想在哪里刮行更改：

如果我检查页面，我会看到值存储在span class=“column GaqNx”下，但我只想为Pinnacle获取这些值，而不想为其他人获取这些值。我怎样才能选择它只刮这个？ 就我所见，下拉列表中元素之间的唯一区别是img徽标

感谢您的帮助。

通过JavaScript动态加载数据，您可以使用此示例加载以下行：

import json
import requests
from datetime import datetime, timedelta


url = r'https://www.sportsbookreview.com/ms-odds-v2/odds-v2-service?query={ openingLines(eid: 3771018, mtid: 401, paid: 20) lineHistory(eid: 3771018, mtid: 401, paid: 20, partid: [450, 1207]) { lines } }'
dt = timedelta(hours=4)  # adjust to your timezone

data = requests.get(url).json()

# uncomment this to print all data:
# print(json.dumps(data, indent=4))

for d in data['data']['lineHistory']:
    t = datetime.fromtimestamp(int(d['lines'][0]['tim']) // 1000) - dt
    v1 = '{:>5} {:>5}'.format(d['lines'][0]['adj'], d['lines'][0]['ap'])
    v2 = '{:>5} {:>5}'.format(d['lines'][1]['adj'], d['lines'][1]['ap'])
    print('{:<20} {} {}'.format(str(t), v1, v2))
