WinPython - news and old stuff.

First good news: the team tells us about the WinPython will come with new release of WinPython.
This will be 3.4.3.7 version of WinPython and this will be great for most of users.
I love this portable python because first is easy to use and can easy test my python scripts.
One goal of this portable python it's the demos. I found some great demos with PyQt4 and networkx.

Also you can use Spyder to make your python scripts.
It's a free open-source development environment for the Python programming language.
This visual interface similar to MATLAB where you can run commands, edit and debug programs, check the values of variables and the definitions of functions, etc.
If you just getting started with Python then just take a look at google.com/edu/python.
The WinPython Control Panel allows to register your WinPython distribution to Windows with Advanced - Register distribution ...:
...and this allow you to:

• associate file extensions .py, .pyc and .pyo to Python interpreter
• register Python icons in Windows explorer
• add context menu entries Edit with IDLE and Edit with Spyder for .py files
• register WinPython as a standard Python distribution in the registry (the same way as the standard Python Windows installers will do)

Also you can use Jupyter Notebook web application.
This allow you to:

WinPython is a free open-source portable distribution of the Python programming language for Windows XP/7/8, designed for scientists, supporting both 32bit and 64bit versions of Python 2 and Python 3.
I use 64bit portable distribution with Python 3.3.5 (v3.3.5:62cf4e77f785, Mar 9 2014, 10:35:05) [MSC v.1600 64 bit (AM
D64)] on win32 and working very well.
From this link you can download it.
WinPython is a free scientific Python distribution for Windows that is portable.It is completely isolated from the rest of the system. Also, WinPython can be installed in a folder (will be put into your download folder)and can be moved anywhere.
You can move on an USB stick and this will make entirely functional.
WinPython is bundled with a lot of existing Python packages.
Also, it includes graphical and command-line utilities to install/uninstall any Python package easily.

This come with spyder 2.3.2 version editor to edit your scripts.

You can use also Qt with Qt designer and you also have a demo application, see:
