Question 10.py

# Write a program that accepts a sequence of whitespace separated words as input
# and prints the words after removing all duplicate words and sorting them alphanumerically.

# Suppose the following input is supplied to the program:

# hello world and practice makes perfect and hello world again
# Then, the output should be:

# again and hello makes perfect practice world

#MY SOLUTION
list_of_words = []
user_words = input('Type something interesting:  ').split()


for words in user_words:
    list_of_words.append(words)
    output = sorted(set(list_of_words))

print(' '.join(output))

#COURSE SOLUTION
word = input().split()

for i in word:
    if word.count(i) > 1:    #count function returns total repeatation of an element that is send as argument
        word.remove(i)     # removes exactly one element per call

word.sort()
print(" ".join(word))
