stopwords.words(english)

`stopwords.words('english')` is a function in the NLTK (Natural Language Toolkit) library, which is used for natural language processing tasks in Python. It returns a list of commonly used stop words in the English language. Stop words are words that are frequently used but generally do not contribute much to the overall meaning of a sentence, and they are often removed in text processing tasks to improve performance and focus on more important words.

Here's an example of how you can use this function:

from nltk.corpus import stopwords

stop_words = stopwords.words('english')
print(stop_words)

This will output a list of stop words in English, such as "a", "an", "the", "in", "is", etc.
