```

This code defines a `FallbackExecutor` class that allows for executing a primary function and, if it fails, attempting one or more fallback functions. It includes error handling within the execute method to manage exceptions and provide meaningful feedback. The example usage demonstrates how to create an instance of the `FallbackExecutor` with both a primary and fallback functions, then execute them.
