Question

请教高手，我在C/C++中嵌入python，用PyImport

Answer 1

拿出一个例子来分析一下,不就是总结吗?

#include <Python.h>

char* python_code1 = "\
import wx\n\
f = wx.Frame(None, -1, 'Hello from wxPython!', size=(250, 150))\n\
f.Show()\n\
";
PyRun_SimpleString(python_code1);

char* python_code2 = "\
import sys\n\
sys.path.append('.')\n\
import embedded_sample\n\
\n\
def makeWindow(parent):\n\
win = embedded_sample.MyPanel(parent)\n\
return win\n\
";
PyObject* globals = PyDict_New();
PyObject* builtins = PyImport_ImportModule("__builtin__");
PyDict_SetItemString(globals, "__builtins__", builtins);
Py_DECREF(builtins);

// Execute the code to make the makeWindow function
result = PyRun_String(python_code2, Py_file_input, globals, globals);
// Was there an exception?
if (! result) {
PyErr_Print();
wxPyEndBlockThreads(blocked);
return NULL;
}
Py_DECREF(result);

// Now there should be an object named 'makeWindow' in the dictionary that
// we can grab a pointer to:
PyObject* func = PyDict_GetItemString(globals, "makeWindow");
