Printing synsets of words in a list in python

Question

I wish to print synonyms of all the words of the list list

    from nltk.corpus import wordnet
    syns = []
    x = 0
    lst = ['performance','camera', 'ram', 'cost', 'battery']
    for r in lst:
        syns = wordnet.synsets(r)
        i = len(syns)
        for x in range(0, i):
            print(syns[x].lemmas()[x].name())

But I get the following error:

  Traceback (most recent call last):
     File "ontology.py", line 9, in <module>
      print(syns[x].lemmas()[x].name()) 
IndexError: list index out of range

Answer 1

I'd recommend using a dictionary indexed by words to hold your synonyms. You will need 3 loops:

1. The outermost loop iterates over each word
2. The mid loop iterates over each synset for a word
3. The innermost loop iterates over each lemma per synset

You can append each lemma to its corresponding synset list.

words = ['performance','camera', 'ram', 'cost', 'battery']
syns = {w : [] for w in words}

for k, v in syns.items():
    for synset in wordnet.synsets(k):
        for lemma in synset.lemmas():
            v.append(lemma.name())

print(syns)
