See the comments inside the code for more details...</p> <p>The only external hardware required is a test lead; oh my, this is technical stuff... ;o)</p> <p>This is for Python 2.x.x, (probably even down to 1.5.2) but it would be just as easy to make it work on 3.x.x. I've already done it......</p> <p>......But I'll let the big guns do that for you...</p> <p>Enjoy finding simple solutions to often VERY difficult problems...</p> <p>Be aware of word wrapping etc...</p> <p>Bazza, G0LCU...</p>

Revision 3. </p> <p>Adds symmetric difference and cartesian product to the Counter class. I had a use case for the former and Raymond H. asked about the latter so I coded the latter from its Wikipedia description.</p>
