Overview
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.

It is a full-featured (see what's inside) Python-based scientific environment:

Designed for scientists (thanks to the integrated libraries NumPy, SciPy, Matplotlib, guiqwt, etc.):
Regular scientific users: interactive data processing and visualization using Python with Spyder
Advanced scientific users and software developers: Python applications development with Spyder, version control with Mercurial and other development tools (like gettext, WinMerge, etc.)

Portable: preconfigured, it should run out of the box on any machine under Windows (without any installation requirements) and the folder containing WinPython can be moved to any location (local, network or removable drive)

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: using the integrated package manager (wppm, as WinPython Package Manager), it's possible to install, uninstall or upgrade Python packages (see WPPM wiki page for more details on supported package formats).

Portable but with optional Windows explorer integration: WinPython is a portable application, so the user should not expect any integration into Windows explorer during installation. However, the WinPython Control Panel allows to "register" your distribution to Windows explorer. This associates file extensions .py, .pyc and .pyo to Python interpreter, Python icons and a context menu entry Edit with IDLE (for .py files only, of course) -- that is exactly what the official Python installer would do to your machine: in other words, you can have it both ways!
