In this tutorial, we will create a "How to Check If a Number is Even or Odd in Python". We will cover the creation of a program that can check if a number is even or odd. The main goal here is to understand the concept of checking the number whether it is even or odd. I will provide a sample program to demonstrate the actual coding of this tutorial.

This topic is very 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 check the number if it is a even or odd. I will do my best to provide you with the easiest method of creating this program, called "Check If a Number is Even or Odd ". 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 checking if a number is even or odd. To do this, simply copy and paste these blocks of code into the IDLE text editor.

while True:
    ret=False
    
    print("\n\n================= Check If a Number is Even or Odd =================\n\n")
    num = int(input("Enter a number: "))
    if (num % 2) == 0:
       print("{0} is Even".format(num))
    else:
       print("{0} is Odd".format(num))
 
 
    
    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 use a while loop to enclose all the code to ensure the continuity of the program. Next, we set variables for the user input and for cheking. Lastly, we use a conditional statement with argument to check the number.
