使用列表理解：
>>> [{'country': country, 'wins': wins} for country, wins in zip(a, b)][{'country': 'USA', 'wins': '10'}, {'country': 'France', 'wins': '5'}, {'country': 'Italy', 'wins': '6'}]使用
json.dumps得到JSON：
>>> json.dumps(... [{'country': country, 'wins': wins} for country, wins in zip(a, b)]... )'[{"country": "USA", "wins": "10"}, {"country": "France", "wins": "5"}, {"country": "Italy", "wins": "6"}]'
