Hi all, I have a little "stupid" question, but what is the purpose of recarray? I have saw that numpy.array supports names, then why using recarray? thanks

It adds attribute access. E.g. records['name'] records.name Note that attribute access goes through a Python method and adds some overhead. If you happen to be iterating through a large array of records and using attribute access on each of the individual record objects, that overhead can be quite substantial. Unfortunately, it appears that record arrays go through the Python __getattribute__ method even ['name'] access is used (although I haven't satisfactorally explained to myself why this is the case). -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
