Your program will read a word (or a whole line) from the user. It will then count the number of vowels in the word (or line) and print put this value. You should ignore the semi-vowel y since determining its role requires dividing words into syllables which is hard to do in English. The program should end when the word END is entered. Example Input and Output: Enter a word: Vowel The word Vowel contains 2 vowels. Enter a word: determining The word determining contains 4 vowels. Enter a word: WILL The word WILL contains 1 vowel. Enter a word: END

Answer:

Following are the program in the Python Programming Language.

def vowel(): #define function

 print("Enter END to Break") #print message

 while(True): #set while loop

   word=input("Enter words: ") #get input from the user

   count=0 #set count to 0

   if(word=="END"): #set if condition

     break #terminate the loop

   else:

     for i in range(len(word)): #set the for loop

       c=word[i] #initialize in c

       if(c=='a'or c=='e' or c=='i'or c=='o'or c=='u'or c=='A'or c=='E'or c=='I'or c=='O'or c=='U'):

         count+=1 #increament in count by 1

     print("The word " , word , " contains " , count, end=" ")#print message

     if(count==1):#check condition

       print("vowel.")

     else:

       print("vowels")

#call the function

vowel()

Output:

Enter END to Break

Enter words: Vowel

The word  Vowel  contains  2 vowels

Enter words: END

Explanation:

Here, we define a function "vowel()" inside it.

  • Print message for the user.
  • Set the while loop and pass condition is True then, get input from the user in the variable "word" then, set variable "count" and initialize to 0.
  • Set if condition to check if the user input "END" then, the loop will terminate.
  • Otherwise, set for loop which continues from the length of the word.
  • Then, we set if statement which checks the vowel in the word, then increment in count by 1.
  • Print the message in the following format which is mentioned in the question.
  • Then, set if-else statement for check count is equal to 1 then print "vowel." Otherwise, it prints "vowels."

Finally, we call the following function "vowel()".
