How should the code be structured to break it into functions?

To structure code and break it into functions in Python, you should:

• Extract logically complete blocks of code into separate functions with clear names.
• Use function parameters to pass input data and return results via return.
• Ensure that functions perform a single specific task (single responsibility principle).
• Avoid overly long functions — it's better to split complex logic into several simpler ones.
• Use docstrings to describe the purpose of the function and its parameters.

Example:

def calculate_area(width, height):
    """Calculates the area of a rectangle."""
    return width * height

result = calculate_area(5, 10)
print(f"Area: {result}")
