Replacing last comma in 'C1, C2, C3' with 'and' so that it reads'C1, C2 and C3'

[Ric Da Force]

Hi guys,

Thank you all for your input!  It was good to see so much convergence in the 
approach! Again, I think that it speaks loudly for the concise way of doing 
thins in Python... Anyway, I have typed in all of the solutions and have 
gained a great understanding of how to do this in future.

Thanks again!
