excel文件实际上无法粘贴到文本中。您的代码在第33行出现异常（在某些情况下，第34行也可能出现异常）：
part\u one\u price=sales\u container.find（“strong”）.text
第二部分价格=销售容器。查找（“sup”）。文本
sales\u containersales\u容器。find（“strong”）None。textpart\u one\u price=None。texttry:#尝试从销售容器中定价和
part_one_price=销售_容器。查找（“强”）。文本
第二部分价格=销售容器。查找（“sup”）。文本
除非异常为e:#如果引发异常
print（f“{product_name}:{e}”）#将产品名称后跟异常打印到控制台
part_one_price=“无法解析价格”#将未找到价格消息分配给var
part_two_price=”“#将部分价格更改为从上一循环清除的空字符串
最后：#一旦尝试或例外完成
价格=第一部分价格+第二部分价格#将价格的两部分合并以备日后使用
您的代码中还有其他一些方面可能需要进行异常处理，以便在运行时以错误的方式访问
