On Windows it is not. You will need to download wheel from that place: http://www.lfd.uci.edu/~gohlke/pythonlibs/ And install it using PIP.

Re: [FAQ] "Best" GUI toolkit for python
If my dusty memory is not wrong they were two projects aiming for GUI designer for wx: wxGlade (with option to generate code for Python) and Boa Contructor. I have no idea however if they are still available or working with newer wx. I prefer for simple stuff Tk for something more sophisticated Qt (PySide or PyQt) On Tuesday, October 18, 2016 at 4:09:46 PM UTC-4, Demosthenes Koptsis wrote: > My favorite GUIs are PyQt and wxPython. > > I prefer PyQt than PySide because PySide seem to me like an abandoned > project. > > Also i prefer PyQt than wxPython because i can design the forms in > QtDesigner easily. > > wxPython and wxWidgets do not have a GUI designer competitor to QtDesigner. > > So, my choice is PyQt ! > > > On 10/18/2016 07:01 PM, pozz wrote: > > Il 18/10/2016 16:56, Michael Torrie ha scritto: > >> On 10/18/2016 02:33 AM, Mark Summerfield wrote: > >>> When I started out I used Qt Designer to produce .ui files (XML) and > >>> then used the Qt uic tool to convert this to C++ (although you can > >>> convert to Python using pyuic).

It is Objective-C. You are mistaken taking NS extensions to function names as a
part of Objective-C. There are not. It is from NextStep/Sun implementation.
Because they are always used a lot of people tend to think that they are part
of Objective-C - but they are not - they are just libraries.
