This Python code defines a class `FallbackExecutor` that wraps two functions—`main_function` and optionally a `fallback_function`. It attempts to execute the main function. If an exception occurs, it catches the error, logs a message, and either executes the fallback function or re-raises the exception if no fallback is provided. The example usage demonstrates how to use this class with simple tasks that might fail under certain conditions.
