如何在Python中为列表中的每个字符串创建子列表？

例如，我有这个列表：

word1 =  ['organization', 'community']

我有一个函数可以从列表中的单词中获取同义词：

from nltk.corpus import wordnet as wn


def getSynonyms(word1):
    synonymList1 = []
    for data1 in word1:
        wordnetSynset1 = wn.synsets(data1)
        tempList1 = []
        for synset1 in wordnetSynset1:
            synLemmas = synset1.lemma_names()
            for s in synLemmas:
                word = s.replace('_', ' ')
                if word not in tempList1:
                    tempList1.append(word)
        synonymList1.append(tempList1)
    return synonymList1


syn1 = getSynonyms(word1)
print(syn1)

这是输出：

[
    ['organization', 'organisation', 'arrangement', 'system', 'administration',
     'governance', 'governing body', 'establishment', 'brass', 'constitution',
     'formation'],
    ['community', 'community of interests', 'residential district',
     'residential area', 'biotic community']
]

^ 上面的输出显示两个的每个同义词集'organization' and 'community'在列表中列出。然后我减少列表的级别：

newlist1 = [val for sublist in syn1 for val in sublist]

这是输出：

['organization', 'organisation', 'arrangement', 'system', 'administration',
 'governance', 'governing body', 'establishment', 'brass', 'constitution',
 'formation', 'community', 'community of interests', 'residential district',
 'residential area', 'biotic community']

^ 现在所有同义词集都保持相同的字符串，没有子列表。我现在想做的就是使所有同义词集newlist1彼此进行子列表。我预计输出会是这样的：

[['organization'], ['organisation'], ['arrangement'], ['system'],
 ['administration'], ['governance'], ['governing body'], ['establishment'],
 ['brass'], ['constitution'], ['formation'], ['community'],
 ['community of interests'], ['residential district'], ['residential area'],
 ['biotic community']]

我正在尝试这段代码：

uplist1 = [[] for x in syn1]
uplist1.extend(syn1)
print(uplist1)

但结果并不是我所期望的：

[[], [],
 ['organization', 'organisation', 'arrangement', 'system', 'administration',
  'governance', 'governing body', 'establishment', 'brass', 'constitution',
  'formation'],
 ['community', 'community of interests', 'residential district',
  'residential area', 'biotic community']]

它显示了两个空列表和两个同义词集列表'organization' and 'community'

如何使同义词集的每个字符串成为一个子列表？

将每个元素放入syn1并包裹在[]使其成为子列表。

要么与append:

uplist1 = []
for i in syn1:
    uplist1.append([i])

或者使用等效的列表理解：

uplist1 = [[i] for i in syn1]
