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.
Since September 2014, Developpement has moved to https://winpython.github.io/
- Designed for regular scientific users: interactive data processing and visualization using Python with Spyder
- Designed for advanced scientific users and software developers: Python applications development with Spyder, version control with Mercurial and other development tools (like gettext, etc.)
- Portable: preconfigured, it should run out of the box on any machine under Windows (without any requirement) and the folder containing WinPython can be moved to any location (local, network or removable drive) with most of the application settings
- Flexible: one can install (or should I write "use" as it's portable) as many WinPython versions as necessary (like isolated and self-consistent environments), even if those versions are running different versions of Python (2.7, 3.x in the near future) or different architectures (32bit or 64bit) on the same machine
- Customizable: The integrated package manager (wppm, as WinPython Package Manager) helps installing, uninstalling or upgrading Python packages
- As WPPM may not support some packages, it's also possible to install or upgrade packages using easy_install or pip from the WinPython command prompt
- A configuration file allows to set environment variables at runtime
For functionality I would give 5. It is an immensely efficient package to use. But because it integrates so many fantastic tools that really shine when combined, stability has been a problem in the last 2 rev. of Python 3.3 and 3.4 on both 32bit and 64bit. As a matter of a fact I have been unable to make the 64bit version run Spyder... Shame But still it is my favourite dev package for Python.
the best python calculation enviroment i have used !
Prefer this distribution of Python over others because I can install it in portable mode. This allows to have multiple versions installed on the same computer, which is great for compatibility testing. Having it installed on a separate disk, I can even resume my work exactly where I left of, when I have to (re)install Windows.
I just tried the version WinPython-32bit-220.127.116.11.exe First impressions on the Ipython2.0 notebook, the Star of this release : - it works, \o/ ! - the new widgets are working on chrome, ie11 and firefox, - more precisely, when playing with the "image processing" example, the experience is : . very good under chrome 34, . a little bit less pleasant under ie 11 (a flickering between images) . end even less pleasant on firefox 28 (a shaking between images) Thanks a lot, Pierre. About features : I whish we could get a python3.4 release in the not too distant future.
