NameError: name 'stopwords' is not defined

Question

I'm getting the error NameError: name 'stopwords' is not defined for some reason, even though I have the package installed. I'm trying to do natural language processing on some feedback reviews. The dataset object is a table with two columns, Reviews (a sentence of feedback) and target variable Liked (1 or 0). Help appreciated, thanks!

Block 1

import re
import nltk
nltk.download('stopwords')

Output 1

   > [nltk_data] Downloading package stopwords to

   > [nltk_data]     /Users/user/nltk_data...

   > [nltk_data]   Package stopwords is already up-to-date!

   > Out[14]: True

Block 2

dataset['Review'][0]
review = re.sub('[^a-zA-Z]',' ' ,dataset['Review'][0])
review = review.lower()
review = review.split()
review = [word for word in review if not word in stopwords.words('english')] **ERROR ON THIS LINE**

Output 2

Solution

you just have to add the following line before using stopwords in your code:

from nltk.corpus import stopwords
