1. Import PorterStemmer and initialize

    from nltk.stem import PorterStemmer
    from nltk.tokenize import word_tokenize
    ps = PorterStemmer()
   

2. Stem a list of words

    example_words = ["python","pythoner","pythoning","pythoned","pythonly"]
   
    for w in example_words:
        print(ps.stem(w))
   

   Result:

3. Stem a sentence after tokenizing it.

    new_text = "It is important to by very pythonly while you are pythoning with python. All pythoners have pythoned poorly at least once."
   
    word_tokens = word_tokenize(new_text)
    for w in word_tokens:
        print(ps.stem(w))   # Passing word tokens into stem method of Porter Stemmer
   

   Result:

    It
