Who uses python on windows?

Who uses IronPython?

What about:

numpy
scipy
pandas
matplotlib?

What we really need is cpython which can call .NET objects seamlessly

Pythonnet

Thanks to:

Brian Lloyd
David Anthoff

pip install --pre pythonnet

Magic time -- imagine

Imagine there's no numpy, it's easy if you try

Imagine there's no batteries, only MS .Net

import clr

from System import Random

rand = Random()

data = pylab.hist([rand.Next() for x in xrange(1000)])

Can use any .NET dll

Put folder containing the DLLs you want to use in your PYTHONPATH


   import clr
   clr.AddReference("Name.Of.Your.Assembly")

   from assembly.name import DotNetClass

from System.Diagnostics import Trace

Trace.WriteLine("message from python")

Thanks

To everyone who made this possible..
