The easiest way to get a Python installation that includes PyLab, Matplotlib, Numpy, Scipy etc is to download Anaconda from : http://www.continuum.io/downloads. In my case I wanted to use the Python v3.3 version under 64 bit Windows. The default Anaconda installation is for v2.x but it is very easy to update to Python v3.3 using conda. form C:\Anaconda type the following command :
conda create -n py33 python=3.3 anaconda
In order to use the v3.3 installation, prepend the following to the PATH environment variable :
C:\Anaconda\envs\py33;C:\Anaconda\envs\py33\Scripts;
Although Anaconda works very well from Python scripts I found that I need to set the following PYTHONPATH environment variable :
set PYTHONPATH=C:\Anaconda\envs\py33;C:\Anaconda\envs\py33\Lib;C:\Anaconda\envs\py33\DLLs
To configure the Visual C compiler for 64 bit mode :
call "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" amd64
For further details on installing the 64 bit Microsoft compiler, please see here :

To compile the app use the following command line :
cl example.c -IC:\Anaconda\envs\py33\include C:\Anaconda\envs\py33\libs\python33.lib /link /MACHINE:X64
If you want to try it, here is a quick test program :
#include "Python.h"
int main()
{
Py_Initialize ();
PyRun_SimpleString ("import sys");
PyRun_SimpleString ("import pylab");
PyRun_SimpleString ("print(sys.version)");
PyRun_SimpleString ("print()");
PyRun_SimpleString ("pylab.plot(range(10))");
PyRun_SimpleString ("pylab.show()");
Py_Exit(0);
return 0;
}
