Submitted by razormist on Wednesday, January 29, 2025 - 22:34.

In this tutorial, we’ll learn how to program "How to Accept a String That Starts with a Vowel in Python." The objective is to understand and implement an efficient method for identifying whether a string starts with a vowel and displaying it accordingly. This tutorial will guide you step by step through the process, ensuring a clear understanding of how to filter and display strings that begin with a vowel. So, let’s get started!

This topic is straightforward to understand. Just follow the instructions I provide, and you’ll complete it with ease. The program I’ll demonstrate will show you the proper way to display a string that starts with a vowel. So, let’s dive into the coding process!

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.

import re
 
def vowel_checker(s):
        pattern = '^[aeiouAEIOU].*'
        if re.match(pattern, s):
                return "String Accepted!"
        else:
                return "String Not Accepted!"
 
while True:
        print("\n================= Accept a String That Starts with a Vowel =================\n\n")
 
        string = input("Enter a string: ")
        print(vowel_checker(string))
 
        opt = input("\nDo you want to try again?(yes/no): ")
 
        if opt.lower() == 'yes':
                ret=False
        elif opt.lower() == 'no':
                ret=True
                print("Exiting program....")
        else:
                print("Please enter yes/no:")
                break
 
        if ret == False:
                continue
        

This program checks whether a given string starts with a vowel (either uppercase or lowercase). It uses a regular expression to match strings that begin with any of the vowels (A, E, I, O, U). If the string starts with a vowel, it prints "String Accepted!"; otherwise, it prints "String Not Accepted!". The user can repeatedly enter strings until they choose to exit.

Output:

There you have it we successfully created How to Accept a String That Starts with a Vowel in Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
