我为这个问题编写代码：
没有下义词的名词同义词集的百分比是多少？您可以使用 wn.all_synsets('n') 获取所有名词同义词集。
这是我的代码：
import nltk
from nltk.corpus import wordnet as wn
all_noun = wn.all_synsets('n')
print(all_noun)
print(wn.all_synsets('n'))
all_num = len(set(all_noun))
noun_have_hypon = [word for word in wn.all_synsets('n') if len(word.hyponyms()) >= 1]
noun_have_num = len(noun_have_hypon)
print('There are %d nouns, and %d nouns without hyponyms, the percentage is %f' %
(all_num, noun_have_num, (all_num-noun_have_num)/all_num*100))
当我运行这段代码时，输出是
<generator object all_synsets at 0x10927b1b0>
<generator object all_synsets at 0x10e6f0bd0>有名词 82115 个，无下位词名词 16693 个，百分比为 79.671193
但如果改变
noun_have_hypon = [word for word in wn.all_synsets('n') if len(word.hyponyms()) >= …
