I'll also code in a function which converts a normal Matrix class to a Sparse Matrix representation. I'll use the List of Non-zero values method, ie a list of (coordinates,value) tuple, sorted coordinate-wise with the earlier coordinate having more precedence.
This is as yet, the most elegant representation I feel. Other advanced formats like the Yale format, introduce complexity to the code but only a slight increase in efficiency, that too for specific cases. Of course, for a complete implementation, more than one representation needs to be coded in, with sympy choosing which to use according to the particular Matrix, but that is a big project in itself, which can take a good part of a GSoC summer.
