How to generate a list of antonyms for adjectives in WordNet using Python

Question

I want to do the following in Python (I have the NLTK library, but I'm not very good with Python, so I wrote the following in a weird pseudocode):

from nltk.corpus import wordnet as wn #Import the WordNet library for each adjective as adj in wn #Get all adjectives from the wordnet dictionary print adj & antonym #List all antonyms for each adjective once list is complete then export to txt file 

This means that I can create a complete dictionary of antonyms for adjectives. I think this should be doable, but I don't know how to create a Python script. I would like to do this in Python, as in the native language of NLTK.

Answer 1

 from nltk.corpus import wordnet as wn for i in wn.all_synsets(): if i.pos() in ['a', 's']: # If synset is adj or satelite-adj. for j in i.lemmas(): # Iterating through lemmas for each synset. if j.antonyms(): # If adj has antonym. # Prints the adj-antonym pair. print j.name(), j.antonyms()[0].name() 

Note that there will be reverse duplicates.
