从两本词典打印

Question

states = {state, abbr}
cities = {abbr, capital}

我想打印出state, abbr, capital或其他3个值的顺序。 我尝试使用以下状态反转键值对;

inv_states = {state: abbr for abbr, state in states.items()}
for abbr, capital in sorted(inv_states.items()):
         print(abbr, ':', capital)

现在我有了：

states = {abbr, state}
cities = {abbr, capital}

然后尝试创建一个新的dict（我不完全理解下面的代码）：

newDict = defaultdict(dict)
for abbr in (inv_states, cities):
         for elem in abbr:
                 newDict[elem['index']].update(elem)
fullDict = newDict.values()
print(fullDict)

但我收到string indices must be intergers错误。

请帮忙。还是我完全走错了路？感谢。

假设您的数据在字典中（它不在您的示例代码中）。抛出你要查找的数据应该非常简单

for state, abbr in states.items():
   print('{0}, {1}, {2}'.format(state, abbr, cities[abbr]))
