In trying to unify the linear algebra syntax, I came across the following behavior:
sage: a=matrix(2,range(4)) sage: a.nrows() 2 sage: a._nrows --------------------------------------------------------------------------- <type 'exceptions.AttributeError'> Traceback (most recent call last) /home/grout/sage/devel/sage-main/sage/misc/<ipython console> in <module>() <type 'exceptions.AttributeError'>: 'sage.matrix.matrix_integer_dense.Matrix_integer_de' object has no attribute '_nrows' sage: a.__dict__ --------------------------------------------------------------------------- <type 'exceptions.AttributeError'> Traceback (most recent call last) /home/grout/sage/devel/sage-main/sage/misc/<ipython console> in <module>() <type 'exceptions.AttributeError'>: 'sage.matrix.matrix_integer_dense.Matrix_integer_de' object has no attribute '__dict__' I noted that the nrows() function just returned self._nrows. So how come I can't access _nrows? Does it have to do with Cython and inheritance?
