Task modified to state action on input of non integer.
Line 6: Line 6:
* return the string corresponding to the index number.
* return the string corresponding to the index number.


The function should reject out-of-range indices by recreating the whole menu before asking again for a number. The function should return an empty string if called with an empty list. For test purposes use the four phrases: 'fee fie', 'huff and puff', 'mirror mirror' and 'tick tock' in a list.
