is_all_vowels

Language/Type: Python string
Write a function named is_all_vowels that returns whether a string consists entirely of vowels (a, e, i, o, or u, case-insensitively). For example, is_all_vowels("ei_e_io") should return True while is_all_vowels("banana") should return False. For this problem, you may assume that a working solution already exists to the previous problem, is_vowel, and you may call it in your solution.
Function: Write a Python function as described, not a complete program.
