C ++ embedded Python

C ++ embedded Python

Add the include/libs directory of python to include/lib directories of VC respectively. In addition, Python does not provide debug Lib. Specifically, Python does not provide python25_d.lib. You can compile PythonSource codeTo obtain python25_d.lib. So, if you want to runProgramYou need to change pyconfig. H (in the python25/include/directory) To The Pragma comment (Lib, "python32_d.lib") in line 283.
Comment (Lib, "python32.lib"), so that python uses non-Debug Lib.

An example with a parameter

Python File
# Filename test2.py <br/> def Hello (s): <br/> Print "Hello, world! "<Br/> Print s

CPP File
# Include <python. h> <br/> int main () <br/>{< br/> py_initialize (); <br/> pyobject * pmodule = NULL; <br/> pyobject * pfunc = NULL; <br/> pyobject * parg = NULL; <br/> pmodule = pyimport_importmodule ("Test2 "); <br/> pfunc = pyobject_getattrstring (pmodule, "hello"); <br/> parg = py_buildvalue ("(s)", "functionwith argument "); <br/> pyeval_callobject (pfunc, parg); <br/> py_finalize (); <br/> return0; <br/>}

In addition, if no statement can be directly executed in The py file, an error occurs.
