Comment:
Hi Anne,
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?
