Code Golf: Count the vowels
Write a function called vcount that takes in a string and returns an integer that is the total number of vowels in the string.
A vowel can be uppercase or lowercase. For the sake of this challenge, the letters A, E, I, O, and U without any accents or adornments are considered vowels. Assume Y does not count as a vowel.
>>> vcount("tweet bird")
>>> vcount("woof doggie")
>>> vcount("fishy fishy")
