class FallbackExecutor:
    """
    A class for executing a primary function and providing fallbacks in case of errors.

    Args:
        primary_func (Callable): The main function to execute.
        fallback_funcs (Dict[Exception, Callable]): A dictionary where keys are exceptions
            that may be raised by the primary_func, and values are functions that will
            handle those exceptions as a fallback.
        max_attempts (int): Maximum number of attempts before giving up. Default is 3.

    Example usage:
        def divide(a: float, b: float) -> float:
            return a / b

        def safe_divide(a: float, b: float) -> Optional[float]:
            try:
                return divide(a, b)
            except ZeroDivisionError as e:
                print(f"Caught an error: {e}")
                return None

        fallback_funcs = {
            ZeroDivisionError: lambda a, b: f"Unable to divide {a} by zero"
