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

    Args:
        primary_executor: The primary function to execute.
        secondary_executors: A list of functions that will be tried as fallbacks if the primary executor fails.
        max_attempts: Maximum number of attempts including the primary execution and all fallbacks (default is 3).

    Example usage:

    ```python
    def multiply(x: int, y: int) -> int:
        return x * y

    def divide(x: int, y: int) -> float:
        return x / y

    # Define a custom exception for handling invalid inputs
    class InvalidInputError(Exception):
        pass

    fallback_executor = FallbackExecutor(
        primary_executor=divide,
        secondary_executors=[multiply],
        max_attempts=3
    )

    try:
        result = fallback_executor.execute(10, 2)
        print(result)  # Expected output: 5.0
    except InvalidInputError as e:
        print(e)

    try:
        result = fallback_executor.execute(10, 0)
        print(result)  # Should not be reached due to division by zero error
    except ZeroDivisionError as e:
        print("Caught an exception:", e)
