Final answer:
St Patrick is credited for driving snakes out of Ireland, but this is a myth. Ireland does not have any native snakes.
Step-by-step explanation:
In Irish folklore, St Patrick is credited for driving snakes out of Ireland. However, it's important to note that this is a myth and not supported by scientific evidence. Ireland does not have any native snakes, so the story is likely a metaphor for St Patrick's efforts to convert the people of Ireland to Christianity.
