→Modifying Abacus
self.abacus.mode.reset_abacus()
self.abacus.mode.reset_abacus()
This will complete the changes in the <code>abacus.py</code>. The method <code>reset_abacus()</code> will have to be defined for each abacus in the <code>abacus_window.py</code>. This can be done by creating that method in the <code>AbacusGeneric</code> class used by all the varieties of abacus. The method may have to be overridden in some abacus subclasses for customization reasons. For instance, <code>reset_abacus()</code> was defined in <code>AbacusGeneric</code> class and then overridden in Schety.

If the changes involve modifying the graphics, then other methods may need to be modified as well. For instance, in order to introduce a reset button that can be clicked to reset the bead positions to the beginning, the following methods had to be modified – all in <code>abacus_window.py</code>:
