[Numpy-discussion] integer array creation oddity

Hi Stéfan,

Is that the recommended way of checking the type of the array? Ususally for
type checkin, I use the isinstance built-in in python, but I see that will
not work in this case. I must admit that I am a little confused by this. Why
is type different from dtype?

Thanks,
Suchindra
