 in  [150]: answer = {} 151]: In pairs for [152]: s.split (','): s = "key1: val1, val2, val3, key2: val11, val22": k, _, v = pair.rpartition (": ") If k: key = k if the key is not in answer: Answer [key] = [] Answer [key] .append (v) .....: in [153]: for k, vals in the north. ['Val1', 'val2', 'val3']
