Just to add , I also found the .stringdosn't do well when there is <br>in the text.

补充一下，我也发现文中存在的.string时候效果不好<br>。

EG:

例如：

 <div class = "Lines">
    <span> First Line <br> Second Line <br> Third Line </span>
  </div>

If we do a soup.find("div",attrs={"class":"Lines}).span.stringwe get a None

如果我们做一个，soup.find("div",attrs={"class":"Lines}).span.string我们会得到一个None

But a soup.find("div",attrs={"class":"Lines}).span.textwe get

但是soup.find("div",attrs={"class":"Lines}).span.text我们得到

First Line
Second Line
Third Line

First Line
Second Line
Third Line

I think the .stringgives a NavigatableStringobject and .textgives a unicode object.

我认为.string给出了一个NavigatableString对象并.text给出了一个 unicode 对象。
