?? Do you really want keys of '2' and 2? How can you have two keys '5'? I guess maybe you want {'1': {'220' : 3}, '2': {'220' : 1, 238 : 4}, '3': {'220' : 1, '238' : 1}, '4': {220 : 2}, '5': {'220: 2, 238 : 1}, '6': {'238' : 2}, '7': {'220' : 1}} > Now I am pretty sure that I need to loop through the first dictionary > and create a defaultdict from the values for each key in that dictionary > but at this point I am having difficulty coming up with the loop. > > I am looking for a satrting point or any suggestions. Do you know how to turn ['220', '238', '238', '238', '238'] into {'220' : 1, '238' : 4} ? If so, then put that code in a loop over the key, value pairs of the dict.
