I just check the first example from introduction to vectorization: http://www.labri.fr/perso/nrougier/from-python-to-numpy/#id5, (add_python and add_numpy) and benchmark results are nearly the same: 75.4ns and 77.7ns accordingly.

Re: From Python to Numpy
#52Does anyone have a recommendation for something similar to this but for Python itself? I have been trying to find something that is not necessarily an intro or crash course book but a book with tips, great explanations, and neat examples (which this e-book(?)/site has). I see that the author has responded to a couple comments here. Thank you for your great work! It's always great to have a nice reference material wit…
There's Fluent Python from OReilly which is a pretty good follow-on for people who are comfortable with the basics and want to know dig into some more advanced features: http://shop.oreilly.com/product/0636920032519.do
Yes, Effective Python is awesome!
Re: From Python to Numpy
#53I'd be very curious to know if there is any impact to choosing Numpy C ordered arrays or Fortran ordered arrays. As a long time Matlab user (since 1993) who moved to Python 3 years ago, I have always defaulted to Fortran order because it was what I was used to and seemed more intuitive. I did play with C ordered arrays but didn't find an advantage in my limited investigation.
There may still be a few routines that expect C-ordered arrays and so require a copy be made when given a Fortran-ordered array --- especially as you extend to one of libraries that use NumPy. For the most, part, however, Fortran-ordered arrays should work well. It all comes down to the expectation of the routine writer.

#54Earlier quoted context omitted.
You mean search? Not everybody uses a Mac ...
Yet somehow you figured out what he meant.
It was not tongue in cheek. I do not know what cmd is. I assume it is a modifier key in an Apple keyboard, since it is not in a Windows keyboard, which I have (although I am on linux).
Sure, I guess he means search, but he could just say that.
Or should I start talking using references to my keyboard shortcuts? I mostly use emacs, very often with custom bindings, or tmux, so it will not make sense to a lot of people.
But hey, it's a free world.
