convert tuple keys of dict into a new dict

Question

I have a dict like this:

{
    (\'America\', 25, \'m\', \'IT\'): 10000,
    (\'America\', 22, \'m\', \'IT\'): 8999,
    (\'Japan\',   24, \'f\', \'I         


        

Answer 1

You can replace your entire try/except with this:

res.setdefault((country, sex, job), {})[age] = cnt

Or you could make res a defaultdict(dict) and then it becomes:

res[country, sex, job][age] = cnt
