Okay, the user wants a complete Python code example. Let me think about what could be useful. Maybe a simple script that does something. Let's start with a basic script that prints "Hello, World!" to the console. That's straightforward and easy to test.

Wait, they mentioned "complete and full." So I need to make sure all parts are included. Let me check if there are any missing elements. Oh, maybe a function or a specific use case. Let's add a function that calculates the sum of two numbers. That would be more interesting.

Now, the code should have comments. Oh, the user might be learning to write code, so adding comments would help. Let me structure it properly. Start with the import statement, then the function, and the main part. Make sure the code runs without errors. Also, include a test case in the main part so it's functional.

Let me test the code step by step. First, the function declaration. Then the parameters. The sum of 5 and 3. Then print the result. That should work. Adding a comment after the function's definition would help explain its purpose.

Is there anything else? Maybe a note about the output or how to run the code. Since the user is asking for a complete example, the code should be self-contained. All variables and functions are defined once, which is good.

So, putting it all together, the code will have a function to add numbers, a main script that uses it, and comments for explanation. That should meet the user's requirements.

Here's a complete Python script that performs a simple task: summing two numbers and printing the result. The script includes:

1. A function to add two numbers
2. A main script that uses the function
3. Comments for explanation

---

✅ Complete Python Code:

# Function to add two numbers
def add_numbers(a, b):
    return a + b

# Main script
result = add_numbers(5, 3)
print("Sum of 5 and 3 is:", result)

---

🧠 Explanation:

• The function add_numbers takes two arguments a and b, and returns their sum.
• In the main script, we call the function with 5 and 3, then print the result.

---

📌 Output:

Sum of 5 and 3 is: 8

This script demonstrates how to write a complete Python program with comments and functionality.
