What is the difference between \%s and \%D in a formatter?

\%s tells the formatter to call the str () function on the argument and since we are coercing to a string by definition, \%s is essentially just performing str (arg). \%d on the other hand, is calling int () on the argument before calling str (), like str (int (arg)), This will cause int coercion as well as str coercion.
