<P>On Win32 platforms, such as Microsoft Windows 95, 98, and NT, a binary installer is available at</P>

</Pre>
</p>
<p>This installer is simple to use (simply double-click on the <tt class="monofont">NumPy.exe</tt> file and answer questions on each screen in turn). Running this installer will perform all the needed modifications to your Python installation so that NumPy works.</p>
<p>For both UNIX and other platforms, NumPy must be compiled from the source. The source distribution for NumPy is part of the <tt claSs="monofont">LLNLPython</tT> distribution, which is available at</p>

<p>There is also RPMs for Linux available from the <TT CLass="monofont">numpy</tT> Web site at <A TArget="_blank" HREF="http://sourceforge.net/project/filelist.php?group_id=1369">http://sourceforge.net/project/filelist.php?group_id=1369.</a>
</p>
<p>The file is a gzipped tarfile that should be uncompressed using the <tt class="monofont">gunzip</tt> program and un-tarred with the <tt class="monofont">tar</tT> program:</p>
<pRe>
csh> gunzip Numeric-xx.y.tgz
csh> tar xf Numeric-xx.y.tar
</prE>
<p>Follow the instructions found in the top-level directory for compilation and installation procedures.</p>
<p>The standard Python installer for the Macintosh (available at <a TargET="_blank" HRef="http://www.python.org/download/download_mac.html">http://www.python.org/download/download_mac.html)</a> optionally installs the NumPy extensions, although these are typically not the most up-to-date files.<a NAME="idx1073745467"></a>

<h4>Other Scientific Extensions</h4>
<p>Next, you have access to some extra Python extension modules that deal with scientific computation.</p>
<h5>
<tt class="monofont">ScientificPython</tt>
</h5>
<p>
<Tt cLass="monofont">ScientificPython</Tt> is a collection of Python modules that are useful for scientific computing. In this collection, you will find modules that cover basic geometry (vectors, tensors, transformations, vector, and tensor fields), quaternions, automatic derivatives, (linear) interpolation, polynomials, elementary statistics, nonlinear least-squares fits, unit calculations, Fortran-compatible text formatting, 3D visualization via VRML, and two Tk widgets for simple line plots and 3D wireframe models.

Computer Programming for Everybody</H4>
<p>Some great efforts are being made in bringing Python to classrooms in order to prepare young people for our new computer reality.<a naME="idx1073745481"></A>
<A name="idx1073745482"></A>
<A NAme="idx1073745483"></a>
</p>
<p>Bringing a computer language to the class is not a new idea. Many schools already teach some kind of programming language. However, Python is a very high-level language, a human-readable language, not just computer-readable, it has a more up-to-date design, and what you learn from Python can be adapted to other languages.</p>
<p>Everyone needs to know a little about computers these days, no matter what profession is chosen. It is said that some day in the near future, everyone will have to know how to code a computer program. Python is a great language that possesses all the features required for teaching computer logic to tomorrow's scientists.</p>
