Python词典在词典打印中的应用

Question

我正试图用随机数字成对地打印'a'的值，但是出现了错误“TypeError:字符串索引必须是整数”

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

编辑最后一行：

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