Pierre, Thanks for the fast and informative answers! On Sun you wrote: > So no, you didn't do anything wrong. What behavior were you expecting ?
I was expecting that calls to self.base would produce identical results for objects of the TestArray class, no matter how these calls are triggered. I used the base attribute to call ndarray functions on my derived class and obviously that failed when base was NoneType. I now realize that this is not a good/robust use of the base attribute and I found a different way to implement the functionality I needed. _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
