Answer 1

You need to instantiate a PorterStemmer object

from nltk.stem import PorterStemmer as ps
from nltk.tokenize import word_tokenize

stemmer = ps()

text = 'my name is pythonly and looking for a pythonian group to be formed by me iteratively'
words = word_tokenize(text)
for t in words:
    print(t, stemmer.stem(t))
