Hi,
Pardon me if I'm reprising an earlier discussion, as I'm new to the list.
But is there a reason that this obscure syntax
A[arange(2)[:,newaxis],indexes]
A[arange(A.shape[0])[:,newaxis],indexes]
is preferable to the intuitively reasonable thing that the Original
Poster did?
A[indexes]
Doesn't it violate the pythonic "principle of least surprise" for the
simpler syntax not to work?
As a casual numpy user, I can't imagine being able to remember the
obscure syntax in order to use the result of an argsort.
curiously,
