How to get a list of antonyms lemmas using Python, NLTK and WordNet?

I would like to generate a list of antonyms lemmas of a given lemma using Python, NLTK, and WordNet. In fact I just want to share a small utility function.

A simple Python and NLTK function that returns a list of antonyms

from nltk.corpus import wordnet as wn

def get_antonyms(input_lemma):
    antonyms = []
    for syn in wn.synsets(input_lemma):
        for lemma in syn.lemmas():
            if lemma.antonyms():
                antonyms.append(lemma.antonyms()[0].name())
    return antonyms
