When a AttributeError is raised inside the get function of a property and if the class has a __getattr__ method defined then this method is called. It is strange behavior because when looking at the traceback it looks like Python doesn't find the property. |

AttributeError is how Python decides that __getattr__ should be called. I believe this is working as designed. |

The problem is that the code of the property could raise an AttributeError. So this error is not showed by the traceback. |

Yup. It's unfortunate, but there's really nothing we can do about it - some protocols use exceptions, and if you raise an exception type that is part of the defined protocol as the result of a genuine error, then you're going to have a fun debugging exercise to deal with. You'll often see a similar misdiagnosis with TypeError in conversion functions that try several different conversion techniques. |
