Hi there -- I have been working on a small Python package whose central data object comes from Numpy (the record array object). I would like to produce documentation that looks like Numpy's, and am planning to follow Numpy's docstring standard. Numpy uses Sphinx to generate documentation (e.g. f

[Numpy-discussion] subclassing from np.ndarray and np.rec.recarray

2009-07-06 Thread Elaine Angelino
Hi -- We are subclassing from np.rec.recarray and are confused about how some methods of np.rec.recarray relate to (differ from) analogous methods of its parent, np.ndarray. Below are specific questions about the __eq__, __getitem__ and view methods, we'd appreciate answers to our specific questio
