如何從BeautifulSoup請求中提取兩個項目

Question

我用beautifulsoup，Python抓取了一些數據。

我如何抽象接下來的兩件事：

1. “數據ASIN =”
2. “數據索引=”

我想擁有值：

1. data-asin = B07F7XYMNN
2. 數據索引= “ 1”

最好是將其存儲在Excel文件中：

DataAsin         DataIndex
B07F7XYMNN         1

我嘗試了兩件事：

soup.select_one（ '數據ASIN ='）

和

soup.select_all（ '數據ASIN ='）

但是沒有結果...任何提示？ 謝謝！
