How to discover table properties from SQLAlchemy mapped object

Question

I have a class mapped with a table, in my case in a declarative way, and I want to \"discover\" table properties, columns, names, relations, from this class:

Answer 1

If declarative base is not used, the answer fails. The following should work no matter how it's initialized

For Class Object:

TableClass.sa_class_manager.mapper.mapped_table.name

For Instance Object:

tableObj.sa_instance_state.mapper.mapped_table.name
