Dynamic classes in Python are well described in this link:http://jelly.codes/articles/python-dynamically-creating-classes. The class is a convenient feature in Python 3 to create classes and instantiate them on the fly. Simulation of large systems by a small class (or dynamic class) cuts both the complexity and time in developing tests. The '# usage shown below' section calculates the stimulusCheckAmt to illustrate the use of the dynamic class to test the change.
