.. _py-builtins-operator-not_equals-range:

*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);

Compares two ranges for inequality.

.. note::

     Ranges are compared by the values hold by range, not by
     specifications of them for example
     ``range(0, 4, 2) != range(0, 3, 2)`` returns ``false``.


Parameters
----------

``lhs``: A range.

``rhs``: Another range.


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

Whether ``lhs`` is not equal to ``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(0);
         py::range<int> rhs(4, 0);

         py::print(lhs != rhs);
     }

**Output**:

.. code-block:: text

     false
