The following cases will be converted:

- &quot;except E, T:&quot; where T is a name:

    except E as T:

- &quot;except E, T:&quot; where T is not a name, tuple or list:

        except E as t:
            T = t

    This is done because the target of an &quot;except&quot; clause must be a
    name.

- &quot;except E, T:&quot; where T is a tuple or list literal:

        except E as t:
            T = t.args
