---------------------

This example shows how a function is turned into a model using decorators.


.. code-block:: python

    #!/usr/bin/env python3 -m modelrunner

    import modelrunner
    
    
    def do_not_calculate(a=1, b=2):
        """This function should not be run."""
        raise RuntimeError("This must not run")
    
    
    @modelrunner.make_model
    def calculate(a=1, b=2):
        """This function has been marked as a model."""
        print(a * b)
