    A class for executing a task with fallback mechanisms in case of errors.

        - max_attempts (int): Maximum number of attempts before giving up, default is 3.

        execute: Attempts to run the primary and fallback functions until success or exhaustion of attempts.

```

This code defines a `FallbackExecutor` class that attempts to execute a primary function and uses fallback functions if an error occurs during the execution of the primary function. The example usage demonstrates how you can use this class with custom tasks.
