Title: Python Program to Check if a Character is a Vowel or Not
Introduction:
In this tutorial, we will create a simple Python program to determine whether a given character is a vowel or not. Vowels are the letters 'a', 'e', 'i', 'o', and 'u'. This program is designed to take a single character as input and provide feedback on whether it is a vowel.
Python Code:
Explanation:
We define a function is_vowel(char) that takes a character as input and checks if it is a vowel. The function converts the character to lowercase using the lower() method for case-insensitive comparison.
The function checks if the character is present in the list of vowels ('a', 'e', 'i', 'o', 'u') and returns True if it is, and False otherwise.
The main() function prompts the user to input a single character and then checks if the input is a single character. If it is, it calls the is_vowel function and prints the result.
Finally, the script checks if it is being run directly (if _name_ == "__main__":) and if so, it calls the main() function.
Usage:
This simple program demonstrates the use of functions and conditional statements to determine whether a character is a vowel in Python.
