What about N.array(3).size N.array([3]).size N.array([3,3]).size Essentially, the [] is being treated as an object when you explicitly ask for an object array in exactly the same way as 3 is being treated as a number in the default case. It's just that '[' ']' is "also" being used as the dimension delimiter and thus the confusion. It is consistent. It's a corner case, and I have no problem fixing the special-case code running when dtype=object so that array([], dtype=object) returns an empty array, if that is the consensus. -Travis > Cheers, > > f > > ------------------------------------------------------------------------- > Using Tomcat but need to do more?
