I believe the problem is that you are not importing the "foo" and "bar"
modules into the __main__ scope. Try using PyImport_ImportModuleEx,
which will allow you to specify the global scope to import the module
into. For example, to import the modules into the __main__ scope you
could do the following:
PyObject* mainmod = PyImport_AddModule("__main__");
PyObject* maindict = PyModule_GetDict(mainmod);
foo = PyImport_ImportModuleEx("foo", maindict , maindict , NULL);
bar = PyImport_ImportModuleEx("bar", maindict , maindict , NULL);
Once the modules are imported into the __main__ scope, you should be
able to use PyRun_SimpleString() to evaluate expressions.
