python - 同时枚举2个Python字典的值？

Question

我有两本词典:

dic_of_dics1 = {1: {"a": "A"}, 2: {"a": "B"}, 3: {"a": "C"}}
dic_of_dics2 = {1: {"d": "20"}, 2: {"d": "30"}, 3: {"d": "40"}}

我想同时枚举字典的值；类似于:Enumerate two python lists simultaneously? :

for index, (value1, value2) in enumerate(zip(dic_of_dics1, dic_of_dics2)):
print (value1, value2, subkey1, subkey2, index) 

期望的输出:

A, 20, a, d, 0
B, 30, a, d, 1
C, 40, a, d, 2

Answer 1

对于您的简化案例:

dic_of_dics1 = {1: {"a": "A"}, 2: {"a": "B"}, 3: {"a": "C"}}
dic_of_dics2 = {1: {"d": "20"}, 2: {"d": "30"}, 3: {"d": "40"}}

for val1, val2 in zip(dic_of_dics1.values(), dic_of_dics2.values()):
    print('{}, {}'.format(list(val1.values())[0], list(val2.values())[0]))

输出:

A, 20
B, 30
C, 40

---

更新(甚至更短):

for i, (d1, d2) in enumerate(zip(dic_of_dics1.values(), dic_of_dics2.values())):
    (k1, v1), (k2, v2) = *d1.items(), *d2.items()
    print(v1, v2, k1, k2, i, sep=', ')

输出:

A, 20, a, d, 0
B, 30, a, d, 1
C, 40, a, d, 2
