The lambda funciton selects the fifth item (index 4) of "i", and "i" represents an item from "irises". The "irises" data was loaded from the "iris_data" CSV file, and the documentation for that file says the fifth attribute is the species.

This is consistent with the name given to the key by the loop, which is "species".
