Vowel Counter 2

Write a program vowel_counter2.py that prints out how many vowels there are in a word entered by the user.

The program should include a function count_vowels(word) that takes the parameter word and goes through it letter by letter, and comparing those with the vowels stored in a list: ['a', 'e', 'i', 'o', or 'u']. That function returns the vowel count to the main program which prints it out.
