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

Softa [21]

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()".
