Introductory Python course. Please make answers simple, I'm really unsure of what to do here.

Write a function that takes, as an argument, a list and a string, and returns a Boolean based whether or not all of the letters in the string appear somewhere in the list. Name your function findLetters(myList, myString). For example, >>> findLetters(["hello", "world"], "hold") should return True, and >>> findLetters(["hello", "world"], "down") should return False
