Talk is cheap. Show me the code

Sure! Here's a simple example code in Python that calculates the sum of two numbers:

def sum_numbers(a, b):
    return a + b

num1 = 5
num2 = 10
result = sum_numbers(num1, num2)
print("The sum of", num1, "and", num2, "is:", result)

When you run this code, it will print: "The sum of 5 and 10 is: 15". This demonstrates a basic function that takes two numbers as input, calculates their sum, and displays the result.
