Error is coming while removing stop words and punctuation

Question

def transform_text(text):
    text = text.lower()
    text = nltk.word_tokenize(text)
    
    y = []
    for i in text:
        if i.isalnum():
            y.append(i)
    
    text = y[:]
    y.clear()
    
    for i in text:
        if i not in stopwords.words('english') and i not in string.punctuation:
            y.append(i)
            
    text = y[:]
    y.clear()
    
    for i in text:
        y.append(ps.stem(i))
    
            
    return " ".join(y)

gives

NameError: name 'stopwords' is not defined

Answer 1

You need to include the following at the top of your module:

from nltk.corpus import stopwords

NameError: name 'stopwords' is not defined means exactly that - you haven't imported or defined what stopwords is yet.

Read the docs for more details.
