We will create a function to find if a given number is even or odd.

Create a function called even_or_odd



In [1]:

    
def even_or_odd(num):
    """
    Prints if the given number is even or odd
    
    Arguments:
    num: number to check 
    """
    
    # use the modulus to see if the division has any reminder
    if num % 2 == 0:
        # if the reminder is 0, then the number is even
        print num, " is even!"
    else:
        # if the reminder is not 0, then its odd
        print num, " is odd!"
    
    return

Call the function with an even number



In [2]:

    
even_or_odd(20)









    



20  is even!

Call the function with an odd number



In [3]:

    
even_or_odd(17)









    



17  is odd!
