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.

Last update: Jan 06, 2023

Overview

pythonnet - Python.NET

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.

Note

The master branch of this repository tracks the ongoing development of version 3.0. Backports of patches to 2.5 are tracked in the backports-2.5 branch.

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 Form

Embedding Python in .NET

You must set Runtime.PythonDLL property or PYTHONNET_PYDLL environment variable starting with version 3.0, otherwise you will receive TypeInitializationException. Typical values are python38.dll (Windows), libpython3.8.dylib (Mac), libpython3.8.so (most other *nix).
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)
{
    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.]

It‘s a prototype of this proposal here to help its discussion.

Modifications are located at file pythonengine.cs, A class named PyScope was added for the variable management and exchanging between .NET and Python.

Several unit tests were given in a new file "src/embed_tests/pyscope.cs" which can be used as examples.

One of the example,

using (Py.GIL())
{
    dynamic ps = Py.CreateScope();
    ps.Set("bb", 100);         //declare a variable
    ps.cc = 10;                  //declare a variable dynamically
    int aa = ps.Eval<int>("bb+cc+3");     //113

    //add a function to the scope, and call it
    //global keyword was used here to show what pyscope can do 
    ps.aa = 0; 
    ps.Exec(
        "def func1():\n" +
        "    global aa \n" +
        "    aa = bb+cc+3 \n"            
    );
    ps.func1(); //call the function
    int aa1 = ps.Get<int>("aa");  //get variable
    int aa2 = ps.aa.As<int>();     //get variable dynamically

    //create a new scope and import the variables
    PyScope ps2 = ps.CreateScope();
    ps2.ImportModule("numpy", "np");
    var aa3 = ps2.Eval<float>("np.sin(bb)");

.NET Core support and CoreCLR embedding - cross-platform API

Looks like with CoreCLR the unmanaged exports "hack" for embedding CLR can be extended by cross-platform hosting API:

https://github.com/dotnet/coreclr/issues/1256

This would allow simple C/C++ code to embed CLR

Current state of .NET Core support:

I'm not sure about the entire history of the license, but it looks to have been chosen when the project originally was hosted on the zope.org community site. As the project as grown, I think its time to update the license to one that provides the same rights and protections but its more commonly known BSD 3-clause

~~As very minimum I would like to update the license from the current zope 2.0 to its more friendly written revision zope 2.1~~

Add python buffer api support
What does this implement/fix? Explain your changes.

Passing data like images from managed to python will be easyer than ever! I implemented the python buffer api which makes copying big chunks of data directly into the python object buffer possible!

You can copy strings to python object:

PyObject array = scope.Eval("bytearray(3)"); byte[] managedArr = new UTF8Encoding().GetBytes(new char[] { 'a', 'b', 'c' }); PyBuffer buf = array.GetBuffer(out bool success, 0); if (success) { buf.WriteToBuffer(managedArr, 0, managedArr.Length); buf.Release(); }

Or copy images to python byte arrays:

byte[] imageArr = LoadImage(); PyObject array = scope.Eval("bytearray(" + managedArr.Length + ")"); PyBuffer buf = array.GetBuffer(out bool success, 0); if (success) { buf.WriteToBuffer(managedArr, 0, managedArr.Length); buf.Release(); }

can not make calls to Python on a separate thread
The following (copies from Example) worked fine using (Py.GIL()) { dynamic test = Py.Import("programs.test_program"); Console.WriteLine(test.func(args)); }

However, the below ends up hanging forever even though it's the same one line program as above. Without the ability to run on a separate thread how can I kill an execution if it takes too long. We deal with massive amount of python scripts at runtime it's gonna be a pain to modify them to terminated the costly computation.

pypy support in pythonnet

cpyext is mature enough (numpy, cython, scipy, pandas soon) to support pythonnet in pypy. In fact pypy used to have a branch which ran on top of CLR (similar to IronPython), but this branch is not maintained.

The use of pypy in .NET is quite popular request:

http://stackoverflow.com/questions/6084697/is-it-possible-to-embed-pypy-into-a-net-application

The only limitation of pypy is 32-bit on Windows and poor support for Python 3+, although the latter is improving with funding from Mozilla.

Also this might be quite nice collaboration with pypy developers due to their level of expertise in python C-API and cffi.

Implicit List conversion breaks backwards compatibility + numpy support
Environment

Computer 1:

Pythonnet version: 2.3, installed via pip I think

Python version: 2.7.12

Operating System: Ubuntu 16.04.2

Computer 2:

Pythonnet version: manual build on master from commit ce14424 (currently 11 commits behind)

Python version: 2.7.12

Operating System: Ubuntu 16.04.2

Details

Description: Python calls .NET function which returns a List. Python then passes the return value, without modification, to a second .NET function which accepts a List. Computer 1 executes this code just fine. On Computer 2, there is no .NET function found that matches the arguments because the return value of the .NET function has been transformed into a Python list.

Python code:

import clr from MyDotNetProject import PythonInterop x = PythonInterop.GetDoubleList() PythonInterop.PrintDoubleList(x)

.NET code:

public class PythonInterop { public static List<Double> GetDoubleList() { var result = new List<Double>(); result.Add(1); result.Add(2); result.Add(3); return result; } public static void PrintDoubleList(List<Double> list) { Console.WriteLine("You list has " + list.Count + " elements"); } }

The Python code works fine on Computer 1. On Computer 2, the PrintDoubleList call produces TypeError: No method matches given arguments

If I print type(x) in Python, Computer 1 gives me a .NET List type while Computer 2 gives me a Python list. I can print x.Count on Computer 1, but I get a missing attribute error on Computer 2.

If I build manually from the 2.3 tag, I get the same (good) behavior as on Computer 1.

It seems that some feature has been partially added to automatically convert .NET objects into Python objects when possible. I suppose this is ok (though I would prefer that not happen because I don't want the mandatory performance hit of converting even when I don't want to convert), but if that's the intention, there must be automatic conversion of Python objects to .NET objects also. One without the other is a critical bug.

Getting an error on python v9.10+ "Cannot create uninitialized instances of types requiring managed activation"
Environment

Pythonnet version: 3.0.1

Python version: 3.11.1

Operating System: windows

.NET Runtime: v4.0.30319

Details

using CLR with 3D app - Solidworks gives me an error:

Unhandled Exception: System.NotSupportedException: Cannot create uninitialized instances of types requiring managed activation. at System.Runtime.Serialization.FormatterServices.nativeGetUninitializedObject(RuntimeType type) at Python.Runtime.ClassObject.tp_new_impl(BorrowedReference tp, BorrowedReference args, BorrowedReference kw) at Python.Runtime.NativeCall.Call_3(IntPtr fp, BorrowedReference a1, BorrowedReference a2, BorrowedReference a3) at Python.Runtime.MetaType.tp_call(BorrowedReference tp, BorrowedReference args, BorrowedReference kw)

What commands did you run to trigger this issue? If you can provide a Minimal, Complete, and Verifiable example this will help us understand the issue.

import clr clr.AddReference("C:\Program Files\SOLIDWORKS 2019\SOLIDWORKS\SolidWorks.Interop.sldworks.dll") <System.Reflection.RuntimeAssembly object at 0x00000285677E4900> from SolidWorks.Interop.sldworks import ISldWorks, SldWorksClass swApp = ISldWorks(SldWorksClass())

This happening only on python 3.10+ on 3.9 it works well.

update: The problem is not with the python version, but using VENV. Outside VENV its working well, but once I setup VENV (any ver) i'm getting the error.

Improved Type Interop with CLR
What does this implement/fix? Explain your changes.

This PR addresses these issues:

Current pythonnet does not allow subclassing from CLR Abstract classes

Running python script with types containing __namespace__, more than once, would throw Type Exists exception

Calling super().VirtualMethod() inside a python-derived virtual method, would result in an infinite loop

Due to the nature of the changes, this is a single PR instead of multiple smaller ones.

After PR merge:

Python types can derive from CLR abstract classes. As before, abstract methods that are not implemented on the python type, will dynamically throw NotImplemented exception.

Specifying __namespace__ is not required to created a ClassDerived anymore. All python derived classes are now represented by ClassDerived in managed memory.

ClassDerived now caches generated types based on namespace, type name, and chain of base classes. This avoids regenerating types or throwing Type Already Exists exceptions. A new format for generated type names include full name of base class and interfaces in the typename. The naming format still ends in the python type name to be backward compatible and passes the unit tests

Example: Full name of derived clr type for python type named SubClass, deriving from BaseClass and implementing BaseInterface1 and BaseInterface2: Python.Runtime.Dynamic.BaseClass__BaseInterface1__BaseInterface2__main__SubClass

Support for one base class and multiple interfaces (Merged some ideas and code from #2028 - Potential merge conflicts)

Derived class can call chosen constructors using super().__init__() pattern.

class SubClass(BaseClassA): def __init__(self, v): super().__init__(v)

Derived class can call base virtual methods using super().method() pattern.

class SubClass(BaseClassA): def DoWorkWith(self, value): r = super().DoWorkWith(value) + 10 return r

Improved virtual method and getter/setter routing. Custom attributes (OriginalMethod and RedirectedMethod) are now used to mark the original and redirected virtual methods. The method name format for OriginalMethod is changed to $"_BASEVIRTUAL__{name}" so it can handle calling original methods on base classes that does not match the name of current class. Previously this was not working.

Other misc refactoring and improvements. No change in behavior.

Does this close any currently open issues?

Potentially (no tests have been done to ensure these issues are resolved)

Added a decoder to be able to handle Func<> parameters
What does this implement/fix? Explain your changes.

It's a decoder to ease use of C# Func<> method arguments. Previously, it was necessary to cast the python lambda expression to System.Func[...] which is very cumbersome for a script-user.

Does this close any currently open issues?

Was not my intention.

Any other comments?

The solution I used is quite complex as it needs the create wrapper types for each Func-Type-Variant. Code creation is implemented using the IL Code Generator, types are cached, generic type arguments are again converted using ToPython()

I hope my change is of some help!

v2.5.0(Jun 14, 2020)
:warning: This release will be the last one supporting Python 2 and non-.NET-Standard builds.

This version improves performance on benchmarks significantly compared to 2.3 and includes various additions and improvements to the library.

Added

Automatic NuGet package generation in appveyor and local builds

Function that sets Py_NoSiteFlag to 1.

Support for Jetson Nano.

Support for __len__ for .NET classes that implement ICollection

PyExport attribute to hide .NET types from Python

PythonException.Format method to format exceptions the same as traceback.format_exception

Runtime.None to be able to pass None as parameter into Python from .NET

PyObject.IsNone() to check if a Python object is None in .NET.

Support for Python 3.8

Codecs as the designated way to handle automatic conversions between .NET and Python types

Changed

Added argument types information to "No method matches given arguments" message

Moved wheel import in setup.py inside of a try/except to prevent pip collection failures

Removes PyLong_GetMax and PyClass_New when targetting Python3

Improved performance of calls from Python to C#

Added support for converting python iterators to C# arrays

Changed usage of the obsolete function GetDelegateForFunctionPointer(IntPtr, Type) to GetDelegateForFunctionPointer<TDelegate>(IntPtr)

When calling C# from Python, enable passing argument of any type to a parameter of C# type object by wrapping it into PyObject instance. ([#881][i881])

Added support for kwarg parameters when calling .NET methods from Python

Changed method for finding MSBuild using vswhere

Reworked Finalizer. Now objects drop into its queue upon finalization, which is periodically drained when new objects are created.

Marked Runtime.OperatingSystemName and Runtime.MachineName as Obsolete, should never have been public in the first place. They also don't necessarily return a result that matches the platform module's.

Unconditionally depend on pycparser for the interop module generation

Fixed

Fixed runtime that fails loading when using pythonnet in an environment together with Nuitka

Fixes bug where delegates get casts (dotnetcore)

Determine size of interpreter longs at runtime

Handling exceptions ocurred in ModuleObject's getattribute

Fill __classcell__ correctly for Python subclasses of .NET types

Fixed issue with params methods that are not passed an array.

Use UTF8 to encode strings passed to PyRun_String on Python 3

Source code(zip)
v2.4.0-rc1(Mar 6, 2019)
Added

Added support for embedding python into dotnet core 2.0 (NetStandard 2.0)

Added new build system (pythonnet.15.sln) based on dotnetcore-sdk/xplat(crossplatform msbuild). Currently there two side-by-side build systems that produces the same output (net40) from the same sources. After a some transition time, current (mono/ msbuild 14.0) build system will be removed.

NUnit upgraded to 3.7 (eliminates travis-ci random bug)

Added C# PythonEngine.AddShutdownHandler to help client code clean up on shutdown.

Added clr.GetClrType (#432)(#433)

Allowed passing None for nullable args (#460)

Added keyword arguments based on C# syntax for calling CPython methods (#461)

Catches exceptions thrown in C# iterators (yield returns) and rethrows them in python (#475)(#693)

Implemented GetDynamicMemberNames() for PyObject to allow dynamic object members to be visible in the debugger (#443)(#690)

Incorporated reference-style links to issues and pull requests in the CHANGELOG (#608)

Added detailed comments about aproaches and dangers to handle multi-app-domains (#625)

Python 3.7 support, builds and testing added. Defaults changed from Python 3.6 to 3.7 ([#698][p698])

Changed

Reattach python exception traceback information (#545)

PythonEngine.Intialize will now call Py_InitializeEx with a default value of 0, so signals will not be configured by default on embedding. This is different from the previous behaviour, where Py_Initialize was called instead, which sets initSigs to 1. (#449)

Fixed

Fixed secondary PythonEngine.Initialize call, all sensitive static variables now reseted. This is a hidden bug. Once python cleaning up enough memory, objects from previous engine run becomes corrupted. (#534)

Fixed Visual Studio 2017 compat (#434) for setup.py
