Title: Python Program to Identify Vowels in a String
Introduction:
In this tutorial, we will create a simple Python program to identify and count the number of vowels in a given string. Vowels are the letters 'a', 'e', 'i', 'o', and 'u'. This program can be useful in various applications where text processing or analysis is required.
Code Example:
Explanation:
The count_vowels function takes an input string as a parameter.
It converts the input string to lowercase using the lower() method to make the comparison case-insensitive.
A list vowels is defined, containing the vowels 'a', 'e', 'i', 'o', and 'u'.
The function initializes a counter variable vowel_count to keep track of the number of vowels.
It iterates through each character in the lowercase input string using a for loop.
Inside the loop, it checks if the character is a vowel by using the in operator to see if it exists in the vowels list.
If the character is a vowel, the vowel_count is incremented.
Finally, the function returns the total count of vowels in the string.
The user is prompted to enter a string, and the count_vowels function is called with the user's input.
The result is then displayed, indicating the number of vowels in the provided string.
Feel free to run this code and experiment with different input strings to see how the program accurately counts the vowels.
