# ANAGRAM: An anagram is direct word switch or word play, the result of rearranging the letters
# of a word or phrase to produce a new word or phrase, using all the original letters exactly once

# We are taking a word and a list. We return the anagrams of that word from the given list and return the
# list of anagrams else return empty list

    	if word != words.lower():
    		if Counter(word) == Counter(words.lower()):
    			anagrams.append(words)
