Question

Lab Assignment | Count vowels

Write a program that will use a while loop to count and display the number of vowels in the string provided as input by the end-user.

This program will consider the letters a, e, i, o, and u (both upper and lower case) to be vowels. The user may enter a single word, a sentence, a paragraph, or nothing at all as input. Be sure to test each possibility.

Python 3 please!

Answer 1

///Program to count the number of vowels in a string that user entered.

def string(sentence):

    count = 0

    sentence = sentence.lower()
    i = 0

///Using while loop

    while (i < len(sentence)):

        if sentence[i] in ['a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U']:

            count += 1
        i += 1;
    return count

if __name__ == '__main__':

    userInput = str(input("No of Vowels in the String user entered is: "))
    count = string(userInput)

    print('Vowel Count: ',count)
