问:使用NLTK的Python拼写检查器

Question

所以我使用NLTK库编写了这行代码

def autospell(text):
        spells = [spell(w) for w in (nltk.word_tokenize(text))]
        return " ".join(spells) 
train_data['Phrase'][:200].apply(autospell) 

我收到了这个错误，告诉我名字拼写没有定义，我不知道这是什么意思，因为我以为它来自NLTK库，或者我错过了什么？

      6         return " ".join(spells)

NameError: name 'spell' is not defined

查看Spell Checker for Python，您可能应该使用autocorrect库。示例代码：

from autocorrect import Speller

spell = Speller(lang='en')

def autospell(text):
        spells = [spell(w) for w in (nltk.word_tokenize(text))]
        return " ".join(spells) 
train_data['Phrase'][:200].apply(autospell)
