python - 嵌套循环列表并动态创建变量

Question

我有一个句子列表，我想每次对两个句子执行一些操作，但不是对所有句子。

例如:

list= ["aaaaa","bbbbb","ccccc","ddddd","eeeee"]
similarity_a-d = sim("aaaaa","ddddd")
similarity_a-e = sim("aaaaa","eeeee")
similarity_b-d = sim("bbbbb","ddddd")
similarity_b-e = sim("bbbbb","eeeee")
similarity_c-d = sim("ccccc","ddddd")
similarity_c-e = sim("ccccc","eeeee")

这就是我的尝试:

similarity={}
for i,vec_lda_topic in enumerate(vec_lda_topics)[:numOfUSs]:
    for j,vec_lda_topic in enumerate(vec_lda_topics)[numOfUSs:]:
        similarity["sim{0}-{1}".format(i,j)] = gensim.matutils.cossim(vec_lda_topics[i], vec_lda_topics[j])
        print('similarity between docs ', i, ' and ',j,': ', similarity["sim{0}-{1}".format(i,j)])

并收到以下错误:

TypeError: 'enumerate' object is not subscriptable

除了错误之外，也许还有更好的方法来做到这一点？

枚举切片列表，不切片枚举列表(两处都这样做)

for i,vec_lda_topic in enumerate(vec_lda_topics[:numOfUSs]):
