I've extracted keywords based on 1-gram, 2-gram, 3-gram within a tokenized sentence

list_of_keywords = []
for i in range(0, len(stemmed_words)):
    temp = []
    for j in range(0, len(stemmed_words[i])):
        temp.append([' '.join(x) for x in list(everygrams(stemmed_words[i][j], 1, 3)) if ' '.join(x) in set(New_vocabulary_list)])
    list_of_keywords.append(temp)

['high blood pressure']
['anxiety', …
