    How to parse words

    import nltk
    from nltk.util import ngrams
    from collections import Counter
    from itertools import chain

    wordSet="gmt a.m at"
    n = 1
    ngrams1= ngrams(wordSet.split(" "), n)

    #Let code begin
    filepath = 'InputText.txt'
    with open(filepath) as fp:
    line = fp.readline()
    while line:
    line = fp.readline()
    if(len(line)!=0):
    #print(line.strip())
    ngrams2= ngrams(line.strip().split(" "), n)
    counter= Counter(chain(ngrams2,ngrams1))
    print([k[0] for k,v in counter.items() if v>1])
