> Thanks for the patch! I am happy to review this. The biggest issue I
have right now is the name of the function 'has_letter'. I think that a
function with that name should just return True or False. I think what I
would prefer is for the method 'cells' to include an optional parameter.
So, something like the following behavior:
> {{{
> sage: t = Tableau([[1,2],[2]])
> sage: t.cells()
> [(0, 0), (0, 1), (1, 0)]
> sage: t.cells(2)
> [(0, 1), (1, 0)]
> }}}
>
> What do you think?
What about:
{{{
sage: t.cells_containing(2)
[(0,1), (1,0)]
}}}
to not pollute ``cells`` with more logic?
