class FallbackExecutor:
    """
    A class that provides a mechanism for executing tasks with fallback strategies in case of errors.

    Args:
        primary_executor: The main function to execute.
        fallback_executors: A list of functions that will be attempted as fallbacks if the primary function fails.

    Usage Example:

    def divide(a, b):
        return a / b

    def safe_divide(a, b):
        try:
            return divide(a, b)

            print("Dividing by zero is not allowed.")
            return 0
        except Exception as e:
            print(f"An unexpected error occurred: {e}")
            return None

    fallback_executor = FallbackExecutor(
        primary_executor=divide,
        fallback_executors=[safe_divide]

    result = fallback_executor.execute(10, 0)
    # Output: Dividing by zero is not allowed.
    #         0
