WinPython – news and old stuff.

First good news: the team tells us 18 hours ago 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:
The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations, visualizations and explanatory text. Uses include: data cleaning and transformation, numerical simulation, statistical modeling, machine learning and much more.

Pillow python module with Python 3.4.1 .

Pillow python module is the python PIL fork created by Alex Clark and Contributors.
As you know the PIL python module is the Python Imaging Library by Fredrik Lundh and Contributors.

The Pillow module version >= 2.0.0 supports Python versions 2.6, 2.7, 3.2, 3.3, 3.4 and no longer supports “import _imaging”. Please use “from PIL.Image import core as _imaging” instead.
Pillow and PIL cannot co-exist in the same environment and you nned to uninstall PIL and after install the Pillow python module.

Now you need to use PIL insead the Pillow. Let see:
