Q : Python Spell Checker using NLTK

So i have this line of code using NLTK library

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

And i got this error telling me that the name spell is not defined, i dont know whats that mean because i thought it was from the NLTK library, or am i missing something somewhere?

NameError                                 Traceback (most recent call last)

NameError: name 'spell' is not defined
Solution

  • Check out Spell Checker for Python, you should probably use the autocorrect library. Example code :

    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)
