        li = i.split( )  # split each line by space
        for j in li:  # loop through each element and append it to the list_of_words list
            list_of_words.append(j)
list_of_words = [i.lower() for i in list_of_words]  # convert every element to lowercase
list_of_words = list(dict.fromkeys(list_of_words))  # remove duplicate elements from the list
list_of_words.sort()  # sort words in alphabetical order
for i in list_of_words:  # print elements in list_of_words
    print(i)
