我想从这个网站（https://www.otcmarkets.com/research/stock-screener）提取各种统计数据。不幸的是，熊猫不认识这些桌子。这是我的密码：

import requests

import pandas as pd

header = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.164 Safari/537.36'}

def Get_table(screen):

    tables = pd.read_html(screen)

    tables.columns = tables.iloc[0]
    
    return tables

screen = requests.get('https://www.otcmarkets.com/research/stock-screener', headers = header).text

table = Get_table(screen)

ValueError:未找到任何表

页面从外部源（URL）加载数据。您可以使用此示例了解如何从API加载数据并创建数据帧：

import json
import pandas as pd

url = "https://www.otcmarkets.com/research/stock-screener/api"
data = json.loads(requests.get(url).json())
df = pd.json_normalize(data["stocks"])
