I want to implement tuple of object in my cython project.
I couldn’t find a way to implement in .pyx file so that I can use it in python.

You can check my get_language method for some reference.

And please help me with my get_value method which has tuple of object as parameter and returns tuple of object value.

In CPP Side

#include "Career.h"
#include "Language.h"

using triple_language_ptr = std::tuple<std::shared_ptr<_Language>, std::shared_ptr<_Language>, std::shared_ptr<_Language>>
    
class _Career{

    std::shared_ptr<_Language> get_language(std::shared_ptr<_Language> value);

    triple_language_ptr get_value(triple_language_ptr value);
}

In Cython Side
[career.pxd]

cdef extern from "Career.h":
    cdef cppclass _Line:

       _Career(...)

       shared_ptr[_Language] get_language(shared_ptr[_Language] value)

       tuple[shared_ptr[_Language], shared_ptr[_Language],shared_ptr[_Language]] get_value(
                 tuple[shared_ptr[_Language], shared_ptr[_Language], shared_ptr[_Language]] value
           )

cdef class Career:
    cdef shared_ptr[_Career] career_ptr

[career.pyx]

cdef class Career:

   def __cinit__(...):
        pass

   def get_language(self, value: Language):
        cdef Language py_lang = Language()
        py_lang.lang_ptr = self.career_ptr.get().get_language(value.lang_ptr)
        return py_lang

   def get_value(self, value: ???):
        # Fill this part of code for me
        pass

Thank you.
