*py::builtins::*\ operator < (:ref:`py::builtins::range <py-builtins-range>`)
=============================================================================

*Defined in* ``<pypp/builtins/range.hpp>``

.. code-block:: cpp

     template <class type>
     constexpr bool operator < (const range<type>& lhs, const range<type>& rhs);

Checks whether a range is less than another range.

.. note::

     Ranges are compared by the values hold by range, not by
     specifications of them.


Parameters
----------

``lhs``: A range.

``rhs``: Another range.


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

Whether ``lhs`` is less than ``rhs``.


Complexity
----------

:math:`O(n)`, where ``n = py::min(lhs.size(), rhs.size())``.


Example
-------

.. code-block:: cpp

     #include <pypp/builtins/range.hpp>
     #include <pypp/builtins/print.hpp>

     int main()
     {
         py::range<int> lhs(9);
         py::range<int> rhs(10);

         py::print(lhs < rhs);
     }

**Output**:

.. code-block:: text

     true
