As far as I can tell PAGE_INFO class is not exposed through SWIG to python API. But my C++ knowledge is minimal at best. @qu1ck might be able to shed more light on this.
That’s correct, PAGE_INFO is not exposed to python right now so you can’t read that object (well not without some nasty hacks). You can open a feature request on gitlab to have that class added to python interface. But be prepared to provide a good use case for why you need it.
