推荐答案

energylist似乎有些标签中不包含锚标签.您需要添加一个条件来优雅地处理这些问题:

It would seem energylist has some tags that do not contain the anchor tag within them. You'll need to add a condition to handle those gracefully:

for stock in energylist:
    try:
        stock_name = stock.find('a').get_text()
        ... # more code
    except AttributeError:
        pass
