BTW, only a frozenset can be included in a set. To check for subsets, either use the issubset function, or the '<' operator (I believe they both call the same code): .>> set(['TRUE','YES']).issubset(set(dir(Tkconstants))) True can be expressed as .>> set(['TRUE','YES']) < set(dir(Tkconstants)) True -- TZOTZIOY, I speak England very best.
