Hello, I've now managed to load a python module using boost::python::exec_file() I can extract variables and run functions from C++ too. But I am stumped on how to pass parameters from C++ to a python function. Not much use without that! I'm using boost::python::extract<std::string>(global["pyFunc"]) to run the function, where the python module may be: ##------------------------ def func1(): return "hello from python" pyFunc = func1() ##----------------------------------- The docs don't seem to elaborate on how to add parameters. There is plenty on calling C++ functions from python...... What I want to do is something like this: // C++ answer = extract<std::string>(global["pyFunc(""hi"", ""there"" )"] ## python def pyFunc( str1, str2 ): return str1+str2 Thanks for putting up with a newbie!
