I am using this code to get all synonyms from the text in document named "answer_tokens.txt" it is only listing the words in the document without the synonyms. can someone check it out?
from nltk.corpus import wordnet
with open('answer_tokens.txt') as a: #opening the tokenised answer file
    wn_tokens = (a.read())
    #printing the answer tokens word by word as opened
    print('==========================================')
    synonyms = []
    for b in word_tokenize(wn_tokens):
            print (str (b))

for syn in wordnet.synsets (b):
                    for l in syn.lemmas(b):
                            synonyms.append(l.name())

It seems to me that there is an indention error at line 11. Line 11 should be in the for b loop.

@Gribouillis i have tried to do the proposed change. still no output this is what its giving

    [

    'Compare

    'dynamic

    'case

    ,
    'video
    '
    ]
    ===================================================
    set()

This is the expected output each word in the text document and its synonyms

the previous code did not have import word_tokenize because i had used the module in a previous code. this should give the same output as shown above

from nltk.corpus import wordnet
from nltk import word_tokenize
with open('answer_tokens.txt') as a: #opening the tokenised answer file
    wn_tokens = (a.read())
    #printing the answer tokens word by word as opened
    print('==========================================')
synonyms = []
for b in word_tokenize(wn_tokens):
            print (str (b))
            for b in wordnet.synsets(b):
                    for l in b.lemmas():
                            synonyms.append(l.name())

print ('==========================================')
print (set (synonyms))

I'm getting this output on kubuntu with python 2.7, with almost the same code

The code is this one, with nltk version 2.0b9

from nltk.corpus import wordnet
from nltk import word_tokenize
with open('answer_tokens.txt') as a: #opening the tokenised answer file
    wn_tokens = (a.read())
    #printing the answer tokens word by word as opened
    print('==========================================')
synonyms = []
for b in word_tokenize(wn_tokens):
            print (str (b))
            for b in wordnet.synsets(b):
                    for l in b.lemmas:
                            synonyms.append(l.name)

print ('==========================================')
print (set (synonyms))

Edit: Code update

Thank you. This is exactly the output we are looking for. I am on windows 10, NLTK 3.2.1
and python 3.4.
Do we have a way to work it out in windows?
