bpl::extract<MyExtensionClass> e(pyobj); if (e.check()) ... Note that you may want to use a reference type as template argument to the boost::python::extract type, if you want to retrieve the object by reference instead of by value. See http://www.boost.org/doc/libs/1_40_0/libs/python/doc/v2/extract.html for details.
