我想知道在Python中指示无效参数组合的最佳实践.我遇到过一些你有这样功能的情况:

def import_to_orm(name, save=False, recurse=False):
    """
    :param name: Name of some external entity to import.
    :param save: Save the ORM object before returning.
    :param recurse: Attempt to import associated objects as well. Because you
        need the original object to have a key to relate to, save must be
        `True` for recurse to be `True`.
    :raise BadValueError: If `recurse and not save`.
    :return: The ORM object.
    """
    pass

唯一令人烦恼的是,每个包装都有自己的,通常略有不同BadValueError.我知道在Java中存在java.lang.IllegalArgumentException- 是否很好理解每个人都将BadValueError在Python中创建自己的s或者是否有另一种首选方法？
