处理除外条款中出现的异常

Question

在我所写的内容中，NoResultException可以在我的try区段或我的except UnexpectedAlertPresentException区段中引发。在这两种情况下，我都想去except NoResultException区块，但只有在try区块中产生NoResultException时才会这样做。这大约是我现在有：

try: 
    # do things 
except UnexpectedAlertPresentException: 
    # do other things, including possibly raise NoResultException 
except NoResultException: 
    # handle exception 

我可以改变它的东西是这样的：

try: 
    # do things 
except UnexpectedAlertPresentException: 
    try: 
     # do other things, including possibly raise NoResultException 
    except NoResultException: 
     # handle exception 
except NoResultException: 
    # handle exception 

处理NoResultException，但我试图避免重复自己。有没有更好的方法来做到这一点？

try: 
    try: 
     # do things 
    except UnexpectedAlertPresentException: 
     # do other things, including possibly raise NoResultException 
except NoResultException: 
    # handle exception 

尽量不要过度使用异常处理控制流程。逻辑可能很难推理，而缩进可能变得非常深刻。
