NameError:未定义名称“synset”

Question

从前面的问题中，我得到了以下代码

print("Array..............\n\n")
tagged=np.array(df['tagged_texts'])
temp = []
for x in tagged: 
    for y in x: 
        temp.append(y) 
tagged = temp
print(tagged)
pos=neg=obj=count=0
for word, tag in tagged:
    ss_set = []
    if 'NN' in tag and swn.senti_synsets(word):
        ss_set = list(swn.senti_synsets(word))
    elif 'VB' in tag and swn.senti_synsets(word):
        ss_set = list(swn.senti_synsets(word))[0]
    elif 'JJ' in tag and swn.senti_synsets(word):
         ss_set = list(swn.senti_synsets(word))[0]
    elif 'RB' in tag and swn.senti_synsets(word):
         ss_set = list(swn.senti_synsets(word))[0]
    if ss_set:
        pos=pos+synset.pos_score()
        neg=neg+synset.neg_score()
        obj=obj+synset.obj_score()
        count+=1
final_score=pos-neg
print(final_score)
df['final_score']=final_score

但是我得到的错误消息是没有定义名称同步集，任何人都可以向我解释为什么会发生这种情况？因为我搜索同样的问题，但我仍然没有找到它

NameError: name 'synset' is not defined

from nltk.corpus import wordnet as wn

导入这个模块可以解决这个问题。
