Question

在我所写的内容中，NoResultException可以在try块或我的except UnexpectedAlertPresentException块中引发。在任何一种情况下，我都想转到except NoResultException块，但只有在NoResultException块中引发try时才会这样做。这几乎就是我现在所拥有的：

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

我可以将其更改为：

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。有没有更好的方法呢？

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。逻辑很难理解，压痕可以变得很深。
