    A class that provides a fallback mechanism for executing functions.
    
    This class is designed to handle situations where an initial function call may fail,
    and a fallback function should be used in its place. It ensures graceful error handling
    by attempting the primary function first and switching to a backup if the primary fails.

    Attributes:
        primary_func (Callable): The main function that will be attempted.
        fallback_func (Callable): The secondary function that will be used as a fallback.
    
    Methods:
        execute: Executes the primary function, falls back to the secondary on failure.
    """

    def __init__(self, primary_func: Callable[..., Any], fallback_func: Callable[..., Any]):
        """
        Initializes the FallbackExecutor with both the primary and fallback functions.

        Args:
            primary_func (Callable): The main function that will be attempted first.
            fallback_func (Callable): The secondary function to use if the primary fails.

        Returns:
            Any: The result of either the primary or fallback function execution.
        
        Raises:
            Exception: If both functions fail, an exception is raised.

This code provides an example of how the `FallbackExecutor` class can be used to create a robust error handling mechanism in Python.
