PYTHON ONLY

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

#feel free to comment,,if u have doubt

my_list = []

def count_vowels(s):

count = 0

vowels = "aeiouAEIOU"

if not s:

return 0

elif s[0] in vowels:

my_list.append(s[0])

return 1 + count_vowels(s[1:])

else:

return 0 + count_vowels(s[1:])

return count_vowels(s[1:])

s = input('Enter a string : ')

count = count_vowels(s)

str = ''.join(map(str, my_list))

print("Vowels in given string : ",str)

print("Number of vowels: ", count)
