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

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

.. code-block:: cpp

     template <class type, class allocator_a, class allocator_b>
     bool operator <= (const list<type, allocator_a>& lhs, const list<type, allocator_b>& rhs);

Checks whether a list is less than or equal to another list.


Parameters
----------

``lhs``: A list.

``rhs``: Another list.


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

Whether ``lhs`` is less than or equal to ``rhs``.


Complexity
----------

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


Example
-------

.. code-block:: cpp

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

     int main()
     {
         py::list<int> lhs{0, 9, 1, 3};
         py::list<int> rhs{0, 9, 1, 3};

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

**Output**:

.. code-block:: text

     true
