Write a program that inputs a sentence from the user (assume no punctuation), then determines and displays the unique words in alphabetical order. Treat uppercase and lowercase letters the same.

Following are the code to this question:

val={} #defining dictionary variable val

def unique_word(i):#defining a method unique_word    

   if i in val: #defining if condition to add value in dictonary          

       val[i] += 1#add values  

   else: #defining else block to update values        

       val.update({i: 1})#updating dictionary

s =input('Enter string value: ') #defining s variable for input string value

w=s.split()#split string value and sorte in w variable

w.sort() #sorting the value  

for i in w: #defining loop for pass value in method unique_word

   unique_word(i)#assign value and calling the unique_word method

for j in val:# defining for loop to print dictionary value  

   if val[j] == 1: #defining if block to check value is unique  

       print(j) #print value

Output:

Enter string value: my name is dataman
