But mainly, see if you > can drop that line of code in Py3. That has been a huge mess. Py3 totally messes things up there. Even the most simply code doesn't work. Take this example:
# CODE #
PyModuleDef moduledef = { PyModuleDef_HEAD_INIT, NULL, NULL, 0, NULL,
NULL, NULL, NULL, NULL };
moduledef.m_name = "MyModule";
moduledef.m_doc = "MyModule";
pModule = PyModule_Create( &moduledef );
PyState_AddModule( pModule, &moduledef );
PyRun_SimpleString( "print( globals() )\n" );
PyRun_SimpleString( "import MyModule\nprint( globals() )\n" );
# CODE #
yields this:
{'__name__': '__main__', '__builtins__': <module 'builtins' (built-in)>,
'__doc__': None, '__loader__': <class
'_frozen_importlib.BuiltinImporter'>, '__package__': None}
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named 'MyModule'
This worked in Py2 and in Py3 created modules are invisible breaking
anything. Why is there no sane documentation providing a working example
for something that elementary. Any ideas what Py3 requires that it does
not write into the docs as one should do?
