Write a function called count_vowels() using what we learned this week about list and recursive function. Here are the requirements:

1. solution uses recursive function. A recursive function has exit condition, and statements that calls itself.

2. function count_vowels takes a parameter of a String type: count_vowels(mystr)

3. function count_vowels returns a integer of how many vowels there are in the string parameter

4. a vowel is any letter in a, e, i, o, u, A, E, I, O, U

5. function count_vowels collects all the vowels in the string parameter, and prints out all the vowels at the end.

6. here's an example of calling the function and the output:

>>> count = count_vowels("banana")

aaa

>>> count
