如何在另一个嵌套列表中搜索列表的元素？

Question

verb_list=[['was', 'playing'], ['watches'], ['guesses'], ['washes'], ['are', 'enjoying'], ['enjoy', 'playing'], ['are', 'wearing'], ['were', 'throwing']]

动词列表显示限制在其中的多个句子的动词

be_verb=['be','am','is','are','was','were','being']

be_动词列表显示自建的辅助动词列表

我必须在“动词列表”中搜索“be_动词”元素，并为每个句子创建单数和复数动词的单独列表

Answer 1

一行列表理解

verbs = [verb[1] for verb in verb_list if verb[0] in be_verb]

Answer 2

for list in verb_list:
    for word in list:
        Current_word = word
        for verb in be_verb:
            Current_verb = verb
            if Current_word == Current_verb:
                print(Current_word, " is a verb to be")
            else:
                continue
