Explanation:-

In this program, we store the string to be sorted in my_str. Using the split() method the string is converted into a list of words. The split() method splits the string at whitespaces.

The list of words is then sorted using the sort() method and all the words are displayed.

Code:-

# Program to sort alphabetically the words form a string provided by the user
my_str = input("Enter a string: ")
# breakdown the string into a list of words
words = my_str.split()
# sort the list
words.sort()
# display the sorted words
print("The sorted words are:")
for word in words:
    print(word)

Output:-
