You need to write an interactive Python program that emulates the behaviour of George's snail as follows :

The snail eats lettuce or cabbage, but not any other food.

The snail does not eat unless it is hungry, so should not be able to over-eat.

If the snail doesn't get fed it will eventually die

Your program should be robust, deal with nonsense input, and provide correct and informative (and possibly amusing ?) responses to user input.
