Python: create a function that takes a word and returns (not print) the number of vowels in the word. Your code should replace and start at the word 'pass' :

def vowel_count(word):  """  Returns the number of vowels in a word (including y).  :param word: the word to search for vowels   >>> vowel_count('Harry')  2  >>> vowel_count('HAIRY')  3  """  # replace pass below with your code pass
