the message `D.setdefault(k[,d])', compiler inform SyntaxError: invalid syntax. I think that it woulld be D.setdefault([k, d]).

The documented syntax is correct.  The '[]' are part of the syntax *specification*, not the syntax itself.  They indicate an optional argument, just as they do in most syntax diagrams.
