''' Purpose: find the word of the longest length amongst the input
'''

# get the words
reply = input( 'Enter text to be examined:: ' )

#words is a list

# need to keep track of the longest word seen so far. It's initialization
# should never prevent the word of longest length being missed

#we havent seen anything yet

# consider the words one by one

for word in words :
    #for each word in words, see if it is longest than the longest word we have seen so far
    #then we want to update longest_word_seen_so_far
    #we are working on problem solving!
    #we are about the current word, and the longest word so far, and their respective lengths
    #now we want to compare these two, and then update if we have seen something better

    # check the word out - compare its length to longest so far
    # if current word is longer than the longest word so far, need to update
    nw = len( word )
    nl = len ( longest_word_seen_so_far )
    #len only works on strings and sequences, will not work on numbers

    #now check the two, update if when nw > nl
    if (  (nw > nl ) == True ) :
        #its true when both sides match (nw > nl) , and false when they arent equal
        #nw > nl is either true or false, so you don't need to check again if it is true or not
        #the if statement only continues if the statement is true, inherently nw > nl is either true or flase
        #but if it helps you learn/visualize , go ahead

        #we know that the new word is the longest word seen so far
        longest_word_seen_so_far = word

        #what happens if they have the same length?
        #go for the first one
        # the comparision is only greater than NOT greater than or equal!
        #if it was greater than or equal, it would update the longest word with the last value that have equal lengths


    else :
        pass
        # pass says - i know what I am doing there is no work needed right here
