I think this sounds like a stupid question, but I searched the C/Api doc
and google but I wasn't able to find any hint:

how can I retrive PyObject pointer if I only know it's name?

What I'd like to do is something like this:

[code]
PyObject* obj = PyFindWhatImLookingFor("w.z.y.x");
[/code]

Of course if I know that w is a module, z is a class and so on I can
search w dictionary than z members than...

But I wonder if there is a way to retrive without knowing what w.z.y.x
means.

Thank you,

Luca.

There is probably a clever/careful way to do it, but most systems that do this
just separate the package/module parts from the object parts:

"w:z.y.x"

Import the module part, then getattr() your way down the object part.
