Counting Vowels in a Sentence¶

Problem¶

You are tasked with creating a Python script that counts the number of vowels in a given sentence. Your program should prompt the user to enter a sentence, and then output the total count of vowels present in that sentence. The program should treat both uppercase and lowercase vowels as equivalent.

Your task is to write a Python script that accomplishes this, utilizing functions and loops as necessary.

In [1]:

def count_vowels(sentence):
    vowels = 'aeiouAEIOU'
    vowel_count = 0
    for char in sentence:
        if char in vowels:
            vowel_count += 1
    return vowel_count

sentence = input("Enter a sentence: ")
print("Number of vowels:", count_vowels(sentence))

Enter a sentence: Hello I am a Sales Expert
Number of vowels: 9

This script defines a function count_vowels that takes a sentence as input and returns the count of vowels in it. It iterates over each character in the sentence and checks if it is a vowel. If it is, it increments the count. Finally, it prints out the total count of vowels in the sentence.
