Question

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 1

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

Step-by-step 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()".
