python json

Question

我要怎样才能拿到a的所有值呢？求解，困扰我半天了

# coding=UTF-8
import json

dict_s = {
    "1": {"a": "one"}, "2": {"a": "two"}, "3": {"a": "three"}
}
for d in dict_s:
    dic = d['a']
    print(dic)

Answer 1

import json

dict_s = {
    "1": {"a": "one"}, "2": {"a": "two"}, "3": {"a": "three"}
}
for d in dict_s: # d 在这里迭代出来的是 dict_s 的 key
    dic = dict_s[d]['a']
    print(dic)
