Sure:
##### main.cpp
#include <set>
std::set<int> f( ) {
return std::set<int>();
}
##### export.py
import os
from pyplusplus import module_builder
here = os.path.abspath( r"." )
mb = module_builder.module_builder_t( [here + r"/main.cpp"],
working_directory=here, indexing_suite_version=2 )
mb.build_code_creator( module_name='set_test_len' )
mb.write_module( here + r'/bindings.cpp' )
##### set_test_len.py
from set_test_len import *
x = f()
len( x )
$ python export.py
