executor = FallbackExecutor(handle_error)

```

This code defines a `FallbackExecutor` class that can be used to safely execute functions with error handling using a fallback mechanism. The example usage demonstrates how to create an instance of the executor and use it to call a function that might raise exceptions, like division by zero.
