This Python code implements a `FallbackExecutor` class designed to handle limited error recovery by executing a primary function and, if an error occurs, invoking one of the pre-defined fallback functions based on the error type. The example usage demonstrates how this might be applied in practice with a simple division operation that has a fallback for handling division by zero errors.
