Yes it’s a function. I do not know who did PLAGIARISM. I learning a NLP course in linkedin the teacher did the same thing!! same data same code!!!!

`def clean_text(text):
`text = “”.join([word.lower() for word in text if word not in string.punctuation])
`tokens = re.split(‘\W+’, text)
`text = [ps.stem(word) for word in tokens if word not in stopwords]
`return text
