I'm laughing slightly here because, at the monthly London Python
Dojo, we often find ourselves implementing board-game mechanics
of one sort or another: Boggle, Battleships, Sliding block,
Connect 4, Noughts-and-Crosses, even things like Game of Life
(which has a board of sorts).

And the "how shall we represent the board?" question is pretty
much the first thing any team asks themselves. And you always
get someone in favour of lists of lists, someone for one long
list, someone who likes a string, someone (me) who likes a sparse
dict keyed on coords, someone else likes nested defaultdicts,
and occasionally more outlandish schemes.

We even went to the extent of having a Dojo a few months back
which was solely about implementing the ideal board for varying
characteristics, but we didn't come to any conclusions :)

(Also I seem to remember that the OP was advised earlier precisely
to abandon lists of lists in favour of something else).
