Hi,
I'm trying to increment an array using indexing and a second array for
increment values (since it might be a little tedious to explain, see below
for a short example).
Using direct indexing, the values in the example are
bincount takes a weights argument which should do exactly what you are
looking for.
Fantastic ! Thanks !

Hi,
there has been a request on the issue tracker for a step parameter to
linspace. This is of course tricky with the imprecision of floating
point numbers.
As a trade off, I was thinking of a step parameter that is used to
calculate the integer number of steps. However to be certain that it

How is that different to arange? Either you specify the number of points

Right. Which is exactly the sort of annoying, content-free code that a
library is supposed to handle for you, so you can save mental energy

Here you go:
In [32]: end = 2.2
In [33]: x = arange(0.1, end, 0.3)

One motivation of this thread was that
adding a step parameter to linspace might make
things easier for beginners.
I claim this thread has put the lie to that,
starting with the initial post. So what is the
persuasive case for the change?
Imo, the current situation is good:
use arange if you

At this time it seems there is more sentiment against it and that is
fine with me. I thought it might be useful for some who normally want
the linspace behavior, but do not want to worry about the right num in
some cases. Someone who
