我想使用python正则表达式从这个站点获得某些值。在

之后，我想从

我试过这个：

regex='class=“main\u tb3”*\n\n
请帮助我，你可以使用下面的正则表达式
对于href值：您可以使用下面的正则表达式
对于href value:，您会发现安装类似以下操作的软件要简单得多：

我将把这个放在这里：=>您不能用正则表达式解析[X]HTML。因为正则表达式无法解析HTML。Regex不是一个可以用来正确解析HTML的工具。请使用它来解析HTML。我将把它放在这里：=>你不能用Regex解析[X]HTML。因为正则表达式无法解析HTML。Regex不是一个可以用来正确解析HTML的工具。请使用它来解析HTML。
