Internally you can use a list in your custom PyObject's struct, (or possibly a tuple if you are sure its kept for internal use - since you'd have to resize it). if you do hold a reference to other PyObject's from a PyTypeObject you define, be sure to fill in PyTypeObject.tp_traverse and include Py_TPFLAGS_HAVE_GC in your tp_flags. for example see:

Another option is to attach a PyObject* dict to your struct and define PyTypeObject.tp_dictoffset for example see: https://svn.blender.org/svnroot/bf-blender/trunk/blender/source/blender/pyth... lines, 72, 156

This has the advantage you can add whatever you like into your object and name your members too, without messing with tp_traverse.

Hello Gang, I have come across the need to dynamically add members to an object at runtime. I would like to attach many objects of a single separate type into a object for processing. Is there a way to dynamically create object members while maintaining the (de)allocation structure? It would be nice to create an array of objects in a single PyObject but then a Py_DECREF() would not work on all of the objects in the array. Has anyone come across the need for this? It would make the module I am creating very easy to use. If not, a short "no" will not hurt my feelings ,')

E.g. w = DateTime() x = DateTime() my_object.add(w) my_object.add(x)

And then have some internal stuff possess those objects, E.g. my_object.combine_dates()
