Bliv hjemme og spar dine penge . <| sep |> Py 3 ' s changes also haven ' t killed Python . But they have killed Python for a certain class of program for which Py 2 is eminently suitable , namely UNIX commandlineoriented programs and other bytesoriented stuff . I am not fully familiar with the infosec community but they seem to be using a lot of Python 3 . Scapy ' s been ported and that does wire protocols . What I think is killing Python is that the core devs are sticking to the GIL , which makes Python 2 or 3 a secondclass citizen in a world where even smartwatches are multicore . Almost all of the other dynamic languages are in the same boat here . Even Node , which is still growing despite of it . I think the issue is money , not a lack of will . It does need to be fixed , but I do not think the problem is as big as people say it is . For me personally the main stumbling block is the deployment of end user applications . Even with pyinstaller , everytime I want to build anything nontrivial into a single file that a nondeveloper enduser can just click on , I run into problems . I am not even going to talk about mobile Python , because I ' ll just end up crying . Yes , I know about Kivy and Bee .
