class FallbackExecutor:
    """
    A class for executing functions with fallbacks in case of errors.

    Args:
        primary_function: The main function to execute.
        fallback_function: The function to use as a fallback if the primary function fails.
        max_attempts: 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) -> float:
    ...     if b == 0:
    ...         raise ZeroDivisionError("Cannot divide by zero")
    ...     return divide(a, b)
    ...
    >>> fallback_executor = FallbackExecutor(
    ...     primary_function=safe_divide,
    ...     fallback_function=lambda a, b: "Undefined",
    ...     max_attempts=3
    ... )
    >>> result = fallback_executor.execute(10, 0)
    >>> print(result)  # Output will be 'Undefined'
