This release has been yanked by its maintainers, and will be ignored by installers, except when explicitly specified.
Consider using release 3.2.1 instead.
Reason given by maintainers: Broken defaulting logic
Python.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. It allows Python code to interact with the CLR, and may also be used to embed Python into a .NET application.
Calling .NET code from Python
Python.NET allows CLR namespaces to be treated essentially as Python packages.
import clr
from System import String
from System.Collections import *To load an assembly, use the AddReference function in the clr module:
import clr
clr.AddReference("System.Windows.Forms")
from System.Windows.Forms import FormEmbedding Python in .NET
You must set Runtime.PythonDLL property or PYTHONNET_PYDLL environment variable starting with version 3.0, otherwise you will receive BadPythonDllException (internal, derived from MissingMethodException) upon calling Initialize. Typical values are python38.dll (Windows), libpython3.8.dylib (Mac), libpython3.8.so (most other Unix-like operating systems).
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)) or mod.func(args, 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.pi * 2 works, 2 * np.pi doesn’t.
Example
static void Main(string[] args)
{
PythonEngine.Initialize();
using (Py.GIL())
{
dynamic np = Py.Import("numpy");
Console.WriteLine(np.cos(np.pi * 2));
dynamic sin = np.sin;
Console.WriteLine(sin(5));
double c = (double)(np.cos(5) + sin(5));
Console.WriteLine(c);
dynamic a = np.array(new List<float> { 1, 2, 3 });
Console.WriteLine(a.dtype);
dynamic b = np.array(new List<float> { 6, 5, 4 }, dtype: np.int32);
Console.WriteLine(b.dtype);
Console.WriteLine(a * b);
Console.ReadKey();
}
