Python字典中字典打印

Question

我正在尝试在 random_dict 中打印成对 'a' 的值，但出现错误 "TypeError: string indices must be integers"，

代码：

coupleascore = 20
couplebscore = 23
couplecscore = 25

judge1scores = [1, 3, 5]
judge2scores = [5, 2, 10]
judge3scores = [7, 5, 9]

random_dic = {'couples': {'a': coupleascore, 'b': couplebscore, 'c': couplecscore} ,'judges': {'1': judge1scores, '2': judge2scores, '3': judge3scores}}

print(key(['random_dic'['couples'['a']]]))

Answer 1

将你的最后一行编辑为：

print(random_dic['couples']['a'])
