Error in calling Python class method from C#
Hi, I am facing issue while calling python class function in C# programme. Can anyone give me hint what is wrong in below programme.While running I am getting error in invoking Initialize() function of class. Python module <Class.py> : def test(): print "Test called" return 1 class ClassTest: def __init__(self) def Initialize (): print " Initialize called" return 1 @staticmethod def Execute(): print "Execute called" return 1 C# Console Programme code snapshot : PythonEngine.Initialize(); using (Py.GIL()) { PyObject testClassModule = PythonEngine.ImportModule("Class"); //Calling module method PyObject result = testClassModule.InvokeMethod("test"); Console.WriteLine("Test method result = {0}", result.ToString()); PyObject classTest = testClassModule.GetAttr("ClassTest"); *classTest.InvokeMethod("Initialize "); -----------------------------> Error* classTest.InvokeMethod("Execute"); } PythonEngine.Shutdown();
Hello, you missed either @staticmethod decorator or the self argument for the Initialize method.

Yes,It will work with this way but i need to create multiple instance of same class.If you see other function (@Execute() ) with static was working. Please give me hint of doing without static. Thanks On Thu, Apr 26, 2018 at 4:54 PM, Stefan Schukat <SSchukat@dspace.de> wrote:
