class FallbackExecutor:
    """
    A class for implementing a fallback mechanism in execution processes.
    
    This class is designed to handle cases where a primary function might fail due to errors or unexpected conditions,
    by attempting an alternative method if available.

    :param primary_func: The main function that will be executed first. It should accept the same arguments as the fallback_func.
    :type primary_func: callable
    :param fallback_func: An optional secondary function to execute in case of failure of the primary function.
    :type fallback_func: callable or None

    Attributes:
        primary_func (callable): The main function that will be executed first.
        fallback_func (callable, optional): An alternative method to call if the primary_func fails. Defaults to None.

    Examples:
        >>> def divide(a: float, b: float) -> float:
        ...     return a / b
        ...
        >>> def safe_divide(a: float, b: float) -> float:
        ...     try:
        ...         return divide(a, b)
        ...     except ZeroDivisionError:
        ...         print("Cannot divide by zero")
        ...
        >>> fallback_executor = FallbackExecutor(safe_divide, None)
        >>> result = fallback_executor.execute(10.0, 2.0)  # Result: 5.0
        >>> result = fallback_executor.execute(10.0, 0.0)  # Result: "Cannot divide by zero", but no exception thrown
