*py::builtins::range::*\ step
=============================

.. code-block:: cpp

     constexpr const long& step() const;

Returns the step value of the range.

The step value defines the difference between two values. This
defines how much to add to a value to get the next one.

.. note::

     The value of this variable is always a non-zero integer.


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

The step value of the range.


Complexity
----------

Constant.


Example
-------

.. code-block:: cpp

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

     int main()
     {
         py::range<int> nums(10, 20, 2);
         py::print(nums.step()));
     }

**Output**:
