class FallbackExecutor:
    """
    A class that provides a fallback mechanism for executing functions.
    
    This class is designed to attempt a primary function execution first,
    and if an error occurs, it will attempt to execute a backup function instead.

    Args:
        primary_func (Callable): The primary function to be executed.
        backup_func (Callable): The backup function to be executed in case of failure.
        *args: Variable length argument list for the functions.
        **kwargs: Arbitrary keyword arguments for the functions.
    
    Raises:
        Any exception that occurs during execution is passed through to the caller.
    """

        Attempts to execute the primary function. If an error occurs,
        it executes the backup function.
        
        Returns:
            The result of the executed function if successful, or re-raises any exception that occurred.

        Example usage:
