You can't/don't need to.

The fundamental problem is that in C++ property names and method names are
in different namespaces and so they can (and sometimes do) clash. In Python
they would be implemented in the same namespace (i.e. the class's
dictionary) hence the problem.

As a convenience you can use the QObject.pyqtConfigure() method to set any
number of properties at once using keyword arguments. You can also set them
when creating a new instance, again using keyword arguments.
