Submitted by razormist on Thursday, February 8, 2024 - 23:49.

In this tutorial, we will create a "How to Count the Vowels in a String in Python". We will cover the basics of creating this program to count the vowels in a string. Our goal is to understand the concept of counting vowels in a string and to display the accurate result. I will provide a sample program to demonstrate the actual coding of this tutorial.

This topic is simple and easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you is how to count vowels in string. I will do my best to provide you with the easiest method of creating this program, called "Count the Vowels in string". So, let's start with the coding.

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 of counting the vowels in string. To do this, simply copy and paste these blocks of code into the IDLE text editor.

def vowel_count(str):
        count = 0
        vowel = set("aeiouAEIOU")
        for alphabet in str:
                if alphabet in vowel:
                        count = count + 1
        
        print("No. of vowels :", count)
 
 
while True:
        ret=False
 
        print("\n\n================= Count the number of vowels in string =================\n\n")
        str = input("Enter your paragraph: ")
 
 
        vowel_count(str)
 
        user_input=input("\n\nTry again? (Yes/No): ")
        print("\n\n")
        if user_input.lower()=='no':
                print("Exit program.")
                break
 
        elif user_input.lower()=='yes':
                ret=True
 
        else:
                print("Wrong input.")
                ret=True
 
 
        if ret:
                continue  

In the provided code, the first step is to create a method containing several blocks of code that handle the counting of vowels. We use a for loop to iterate through the string, checking each character to determine if it is a vowel, and then appending it to a variable.
