To implement a function that calculates the sum of two numbers in Python, the best approach is to keep it simple, readable, and efficient. Here's the optimal solution:

Step-by-Step Explanation:

1. Define the function: Use a descriptive name (e.g., add_two_numbers) to clearly indicate its purpose.
2. Accept two parameters: These will be the numbers to sum (supports int, float, or any numeric type in Python).
3. Return the sum: Use Python's built-in + operator to add the two parameters directly.

Example Code:

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

Optional: Add Type Hints (for Clarity)

To make the function more explicit about input/output types (Python 3.10+ for union types):

def add_two_numbers(a: float | int, b: float | int) -> float | int:
    return a + b

Why This Is the Best Approach:

• Efficiency: Directly uses Python's optimized arithmetic operations (no unnecessary overhead).
• Readability: The function name and logic are self-explanatory.
• Flexibility: Works with all numeric types (integers, floats, even complex numbers if needed).

Usage Example:

print(add_two_numbers(5, 3))  # Output: 8
print(add_two_numbers(2.5, 4.5))  # Output:7.0

This implementation is clean, maintainable, and aligns with Python's "simplicity first" philosophy.
