how can I remove suffix using the nltk package in python?

Question

I changed "stem" to "suff", but it went wrong. Does anybody know how to use the suff fuction?

from nltk.stem.snowball import SnowballStemmer
from nltk.stem import arlstem
    for j in range(0 , len(contextsWorld_1)):
        a = stemmer.stem(contextsWorld_1[j])
        contextsWorld_1_1.append(a)
    print(contextsWorld_1_1)

the website of nltk.stem package the error

Answer 1

suff is a method of the arlstem module, which is designed for stemming Arabic text.

If the goal is to remove the suffixes of English words, we want to stem them with something like the English SnowballStemmer. Here is a minimal example:

from nltk.stem.snowball import SnowballStemmer

words = ["running", "jumping", "playing"]
stemmed_words = []

stemmer = SnowballStemmer(language="english")

for word in words:
    a = stemmer.stem(word)
    stemmed_words.append(a)

print(stemmed_words)

Output:

['run', 'jump', 'play']
