This could be written more simply as return transDict.get(c, c) > Then if you have your data: > > data = { 1:('a','b','c'), 2:('a','c'), 3:('b','c'), 4:('a','d')} > > You can translate it as: > > for key in data.keys(): > data[key] = map(transFn, data[key]) I would use a list comprehension and dict.get(): for key, value in data.items(): data[key] = [ transDict.get(i, i) for i in value ] Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
