Issues Found 1. ZeroDivisionError – The function does not handle division by zero, which will cause the program to crash. 2. Lack of Type Checking – The function does not validate the input types, which could lead to unexpected errors if non-numeric values are passed. 3. No Error Handling – There is no mechanism to catch and gracefully handle exceptions. 4. Missing Type Hints – The function lacks type annotations, which improve readability and maintainability. Optimized Code with Explanations def divide_numbers(a: float, b: float) -> float | str: """Safely divides two numbers, handling division by zero.""" try: return a / b except ZeroDivisionError: return "Error: Division by zero is not allowed." # Example usage print(divide_numbers(10, 0)) # Outputs: Error: Division by zero is not allowed. print(divide_numbers(10, 2)) # Outputs: 5.0 Improvements & Best Practices 1. Exception Handling – Using try-except prevents crashes and provides a meaningful error message. 2. Type Hints – Specifying a: float, b: float -> float | str improves code clarity. 3. Returning an Error Message Instead of Raising an Exception – Instead of crashing, the function returns a user-friendly message. 4. Docstrings – A short description improves maintainability. Would you like additional enhancements, such as logging or stricter type enforcement? 🚀
