Question

Can anyone please tell me what is wrong with this script. I am a python newb but i cant seem to figure out what might be causing it not to function.

def find_vowels(sentence):

    """
    >>> find_vowels(test)
    1

    """

    count = 0
    vowels = "aeiuoAEIOU"
    for letter in sentence:
        if letter in vowels:
            count += 1
    print count

if __name__ == '__main__':
    import doctest
    doctest.testmod()

Answer 1

Besides the fact that you’re returning a count but expecting a string of vowels, as others have said, you must also change the line

>>> find_vowels(test)

to

>>> find_vowels('test')

You forgot the quotes!
