• boost::python::extract:

  → py::isinstance(py::object), py::cast(py::object)

  • compatibility wrapper in lib/pyutil/compat.hpp

• boost::python::object(a) to wrap any object as python object:

  → py::cast(a);

• no_init: just not specifying init<>()??

• pickle: ?

• inherit from boost::noncopyable?

• add_property → def_property (getter and setter), def_property_readonly (getter only)

• def_readonly, def_readwrite: unchanged

• how to inherit from boost::noncopyable in py::class_??

• py::dict:

  • bp: `has_key`, pb11: `contains`
    

  • bp::api::del(dict,key); pb11: dict.attr("pop")(key)

• !! no single way to get py::object from anything:

  • py::cast(...) works only for non-python types
  • py::object(...) works only for python types

Return value policies

return_by_value → py::return_value_policy::copy
