The definition is for assignment, and does not concern binary ops, so it behaves as expected. The inplace operation >>> x += y is defined as equivalent to binary op followed by assignment >>> x[:] = x + y as far as the missing values are concerned. > However, doesn't this have the issue that Nathaniel brought up earlier: > commutativity > > unignore(x + y) != unignore(y + x) As the definition concerns only what happens on assignment, it does not have problems with commutativity. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
