    # Simulate failure by raising an exception

```

This example demonstrates a `FallbackExecutor` class that tries to execute the primary function and uses a list of fallback functions if an error occurs during execution. The `run` method attempts each function in the fallbacks list until it succeeds or exhausts all options, raising an exception if no fallback is successful.
