36+ < p > WinPython is a free open-source portable
37+ distribution of the < a href ="http://www.python.org/ " rel ="nofollow "> Python
38+ programming language</ a > for Windows XP/7/8, designed for scientists,
39+ supporting both 32bit and 64bit versions of Python 2 and Python 3. </ p >
40+ < p > < img style ="width: 901px; height: 97px; " alt ="WinPython_Launchers " src ="images/winpython_launchers_2741.png "> </ p >
41+ < p > It is a full-featured (see < a href ="https://sourceforge.net/p/winpython/wiki/PackageIndex "> what's
42+ inside</ a > ) Python-based scientific environment: </ p >
43+ < ul >
44+ < li > Designed for scientists (thanks to the
45+ integrated libraries < a href ="http://numpy.scipy.org/ " rel ="nofollow "> NumPy</ a > , < a href ="http://www.scipy.org/ " rel ="nofollow "> SciPy</ a > , < a href ="http://matplotlib.sourceforge.net/ " rel ="nofollow "> Matplotlib</ a > ,
46+ < a href ="http://code.google.com/p/guiqwt/ " rel ="nofollow "> guiqwt</ a > , etc.): </ li >

48+ < li > Regular < strong > scientific users</ strong > :

50+ < li > < strong > Advanced scientific users and

52+ Python applications development with < a href ="http://code.google.com/p/spyderlib/ " rel ="nofollow "> Spyder</ a > ,
53+ version control with Mercurial and other development tools (like
54+ gettext, etc.) </ li >
55+ </ ul >
56+ < li > < strong > Portable</ strong > : preconfigured, it
57+ should run out of
58+ the box on any machine under Windows (< a href ="https://sourceforge.net/p/winpython/wiki/Installation "> without
59+ any requirement</ a > ) and the folder containing WinPython< a href ="http://code.google.com/p/winpython/w/edit/WinPython "> ?</ a > can

61+ of the < a href ="https://code.google.com/p/winpython/wiki/Installation#Settings " rel ="nofollow "> application settings</ a > </ li >
62+ < li > < strong > Flexible</ strong > : one can install (or
63+ should I write "use" as it's portable) as many WinPython versions as
64+ necessary (like isolated and self-consistent environments), even if
65+ those versions are running different versions of Python (2.7, 3.x in
66+ the near future) or different architectures (32bit or 64bit) on the
67+ same machine </ li >
68+ < li > < strong > Customizable</ strong > : </ li >
69+ < ul >
70+ < li > The integrated package manager (wppm, as
71+ WinPython Package Manager) helps installing, uninstalling or upgrading
72+ Python packages (see < a href ="https://sourceforge.net/p/winpython/wiki/WPPM "> WPPM wiki page</ a >
73+ for more details on supported package formats) </ li >
74+ < li > As < a href ="https://sourceforge.net/p/winpython/wiki/WPPM "> WPPM</ a > may not
75+ support some packages, it's also possible to install or upgrade
76+ packages using < tt > easy_install</ tt > or < tt > pip</ tt > from the
77+ WinPython command prompt </ li >
78+ < li > A configuration file allows to set < a href ="https://sourceforge.net/p/winpython/wiki/Environment "> environment

82+ < p > WinPython vs. Python(x,y): < strong > WinPython is
83+ not an
84+ attempt to
85+ replace < a href ="https://code.google.com/p/pythonxy/ " rel ="nofollow "> Python(x,y)</ a > </ strong > ,
86+ this is just something different (see < a href ="https://sourceforge.net/p/winpython/wiki/Roadmap "> motivation and
87+ concept</ a > ): more flexible, easier to maintain, movable and less
88+ invasive for the OS, but certainly less user-friendly, with less
89+ packages/contents and without any integration to Windows explorer.</ p >

93+ or

95+ < p > WinPython is a portable application, so the user
96+ should
97+ not
98+ expect
99+ any integration into Windows explorer during < a href ="https://sourceforge.net/p/winpython/wiki/Installation "> installation</ a > .
100+ However, the < a href ="https://sourceforge.net/p/winpython/wiki/ControlPanel "> WinPython
101+ Control Panel</ a > allows to "register" your distribution to Windows
102+ (see screenshot below). </ p >
103+ < p > < img style ="width: 453px; height: 152px; " alt ="WinPython_Register " src ="images/wpcp_register_2741.png "> </ p >
104+ < p > Registering your WinPython installation will: </ p >
105+ < ul >
106+ < li > associate file extensions < tt > .py</ tt > , < tt > .pyc</ tt >
107+ and < tt > .pyo</ tt >
108+ to Python interpreter </ li >
109+ < li > register Python icons in Windows explorer </ li >
110+ < li > add context menu entries < tt > Edit with IDLE</ tt >
111+ and < tt > Edit
112+ with Spyder</ tt > for < tt > .py</ tt > files </ li >
113+ < li > register WinPython as a standard Python
114+ distribution
115+ (standard
116+ Python Windows installers will see WinPython in Windows registry) </ li >
117+ </ ul >
118+ That is exactly what the official Python installer would do to your
119+ machine: in other words, you can have it both ways! </ div >
