我们如何识别单词的同义词和反义词？引理将是同义词，然后您可以使用.antonyms来查找引理的反义词。因此，我们可以填充一些列表，如：

import nltk

from nltk.corpus import wordnet

synonyms = []

antonyms = []

for syn in wordnet.synsets("good"):

for l in syn.lemmas():

synonyms.append(l.name())

if l.antonyms():

antonyms.append(l.antonyms()[0].name())

print(set(synonyms))

print(set(antonyms))

输出将是两组同义词和反义词
