I am trying to write a C# program that runs a python script. It, looks something like this: PythonEngine.Initialize(); PyList pyargv = null; PyObject sys = PythonEngine.ImportModule("sys"); if (sys.HasAttr("argv")) { pyargv = sys.GetAttr(new PyString("argv")) as PyList; } else { pyargv = new PyList(); foreach (string arg in argv) { pyargv.Append(new PyString(arg)); } } sys.SetAttr("argv", pyargv); string dir = System.IO.Path.GetDirectoryName(argv[0]); if (!String.IsNullOrEmpty(dir)) { PyList path = new PyList(sys.GetAttr("path")); PyObject pydir = new PyString(dir); if(!path.Contains(pydir)) { path.Append(pydir); } } PyObject module = PythonEngine.ImportModule(System.IO.Path.GetFileNameWithoutExtension(argv[0])); if(module!=null) module.Dispose(); PythonEngine.Shutdown(); So far, so good. At this point you may ask why I'm bothering and not just using python.exe. Just trust me, that it's a bit specialized, and I need to do a few other things. Namely, make some changes to the global namespace. So, I added a function to PythonEngine to return new PyDict(Runtime.PyEval_GetGlobals()); So that I can start adding some objects to it that the script can make use of. Unfortunately, PyEval_GetGlobals returns 0. It does so in PythonEngine.RunString as well. This seems kind of strange to me. What am I doing wrong? Thanks, Mark.
