*py::builtins::in::*\ container
===============================

.. code-block:: cpp

     constexpr const type& container() const;

Returns constant reference to the iterable object referenced by
the ``py::builtins::in`` object.


Return value
------------

Constant reference to the iterable object referenced by the
``py::builtins::in`` object.


Complexity
----------

Constant.


Example
-------

.. code-block:: cpp

     #include <pypp/builtins/list.hpp>
     #include <pypp/builtins/in.hpp>
     #include <pypp/builtins/print.hpp>

     int main()
     {
         py::list<int> nums = {0, 1, 2, 3, 4, 5, 6};
         py::print(nums == py::in(nums).container());
     }

**Output**:

.. code-block:: text

     true
