Python for .NET is a package that gives Python programmers nearlyseamless integration with the .NET Common Language Runtime (CLR) andprovides a powerful application scripting tool for .NET developers. Itallows Python code to interact with the CLR, and may also be used toembed Python into a .NET application.

Python for .NET allows CLR namespaces to be treated essentially asPython packages.

import clrfrom System import Stringfrom System.Collections import *

To load an assembly, use theAddReference function in theclrmodule:

import clrclr.AddReference("System.Windows.Forms")from System.Windows.Forms import Form

• All calls to python should be inside ausing (Py.GIL()) {/* Your code here */} block.
• Import python modules usingdynamic mod = Py.Import("mod"), thenyou can call functions as normal, egmod.func(args).
• Usemod.func(args, Py.kw("keywordargname", keywordargvalue)) ormod.func(args, keywordargname: keywordargvalue) to apply keywordarguments.
• All python objects should be declared asdynamic type.
• Mathematical operations involving python and literal/managed typesmust have the python object first, eg.np.pi * 2 works,2 * np.pi doesn't.

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

Output:
