I'd rather turn the question around: how much sanity checking is necessary or useful? You'll find the answer is "surprisingly little" compared to your experience in Java.
I'm looking for a pythonic approach to sanity checking. From what I read elsewhere, sanity checking belongs in the unit tests and/or library classes designed for other people to use. I haven't seen many examples of sanity checks that is common in Java.
For example, you don't need to explicitly check whether the color is present in your dictionary, because it'll give you a KeyError if you look up a bad key.
Without the sanity check against the constant dictionary, the color variable could be anything (it should be a string value). Looking at the code again, I should relocate the sanity checks in the Piece base class.
Why does the len of positions need to be 16?
The positions variable is list of coordinates for 16 chess pieces (eight pawns, two rooks, two knights, two bishops, a king and a queen) for each color, locating the pieces on either the bottom quarter (i.e., [(1,1), ..., (2,8)]) or the top quarter (i.e., [(7,1), ..., (8,8)]) of the board.
