Question

我正在尝试捕获以下两个异常：

class TestException:
    def __init__(self):
        self.x = [1, 2, 3]

def main():
    test_exception = TestException()
    try:
        test_exception.y[1] = 4.0
    except (IndexError, AttributeError) as e:
        raise e('Why does this not work?')

if __name__ == '__main__':
    main()

但出现以下错误：

TypeError：“ AttributeError”对象不可调用

为什么会这样？因为以下方法可以正常工作：

raise AttributeError('This does work!')

感谢您的帮助。

Answer 1

从@jonrsharpe开始，以下工作正常：

[SEVERE] built_value_generator:built_value on lib/client.dart (cached):
Unknown error in BuiltValueGenerator for myproject|lib/client.dart.
NoSuchMethodError: The method 'getParsedLibraryByElement' was called on null.
Receiver: null
Tried calling: getParsedLibraryByElement(Instance of 'LibraryElementImpl')

或

raise type(e)('This works now.')

捕获2个异常并使用“ as”无法正常工作
