Python for .NET is a package that gives Python programmers nearly seamless integration with the .NET Common Language Runtime (CLR) and provides a powerful application scripting tool for .NET developers.

Features not yet integrated into the main branch:

• Python 3 support
• Subclassing managed types in Python

• All calls to python should be inside a "using (Py.GIL()){/* Your code here */}" block.
• Import python modules using dynamic mod = Py.Import("mod"), then you can call functions as normal, eg mod.func(args).
• Use mod.func(args, Py.kw("keywordargname", keywordargvalue)) to apply keyword arguments.
• All python objects should be declared as 'dynamic' type.
• Mathematical operations involving python and literal/managed types must have the python object first, eg np.pi2 works, 2np.pi doesn't

EG:

staticvoidMain(string[]args){using(Py.GIL()){dynamicnp=Py.Import("numpy");dynamicsin=np.sin;Console.WriteLine(np.cos(np.pi*2));Console.WriteLine(sin(5));doublec=np.cos(5)+sin(5);Console.WriteLine(c);dynamica=np.array(newList<float>{1,2,3});dynamicb=np.array(newList<float>{6,5,4},Py.kw("dtype",np.int32));Console.WriteLine(a.dtype);Console.WriteLine(b.dtype);Console.WriteLine(a*b);Console.ReadKey();}}
