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. It allows Python code to interact with the CLR, and may also be used to embed Python into a .NET application.
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 Form
- 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, egmod.func(args). - Use
mod.func(args, Py.kw("keywordargname", keywordargvalue))ormod.func(args, keywordargname: keywordargvalue)to apply keyword arguments. - All python objects should be declared as
dynamictype. - Mathematical operations involving python and literal/managed types
must have the python object first, eg.
np.pi * 2works,2 * np.pidoesn't.
static void Main(string[] args)
{
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 = 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();
}
}Output:
1.0 -0.958924274663 -0.6752620892 float64 int32 [ 6. 10. 12.]
