代码返回空数据框，理解逻辑有问题

Question

这段代码是从一个名为cafef的网站爬取股票数据。输入是网站链接和来自该网站 HTML 的元素，预期输出是包含日期、价格、数量等股票数据的表格。但是，该代码不起作用，它返回一个空数据框。我不明白除了块之外的第二次尝试，所以我无法调试运行这段代码。大佬们帮我解释一下

 d = {'Stock': stock_id,'Date': date,'Close': close,'Volume': volume}
 df = pd.DataFrame(data=d)
 df.to_csv(stock+".csv", index=False)
 return df
print(crawl('ABC'))

我试图找到 xpath 元素，但我没有找到
