当我在最后一行的最后一行键入. text时，它给我一个错误，这是错误。我想提取价格，有什么想法吗？

print(soup.find("div",{"class": "intraday__data"}).find("h3",{"class": "intraday__price"}).find("bg-quote")).text
AttributeError: 'NoneType' object has no attribute 'text'
您正在键入。始终返回print（）和print之后的textNone。改为这样做：
print(
soup.find("div", {"class": "intraday__data"})
.find("h3", {"class": "intraday__price"})
.find("bg-quote")
.text
) # <-- NOT .text here!
