''' Purpose: find the words of maximum length in user text
'''

# get the words
reply = input('Enter text: ')
words = reply.split()

# = is assignment, == is the equivalence test (relation)
# <=, >= are also relation operators

# consider the words one by one to find a shortest word
shortest_seen = words[0]  # so far nothing has been seen
# Initialize it to the first word in the list and then
# continue testing from there to see if you find anything shorter!
# If you're trying to find the shortest, you can't
# start with the empty string because nothing is shorter
# than the empty string!
for word in words:  # consider each word in turn
    nw = len(word)  # get its length
    ns = len(shortest_seen)  # get the length of the shortest seen so far
    print('word = ', word, '| Shortest word seen so far = ', shortest_seen)
    if ( nw < ns ):  # compare the two lengths
        shortest_seen = word  # if current word is longer, update shortest seen

print( shortest_seen )

# In general you can have as many test expressions in
# your if statement as you want so you could do
# a<b<c like just in general (not for this problem)


# print result

# print(shortest_words)
