Solution Exercise 16

Write a function that takes a character (i.e. a string of length 1) and returns True if it is a vowel, False otherwise.

def vowel(char):
    vowels = "aeiouy"
    #Make sure that the character that is passed in
    #is lower case so it can be found in the
    #vowels string
    if char.lower() in vowels:
        return True
    else: 
        return False

def main():
    if vowel("B"):
        print("Yes")
    else:
        print("No")
    
if __name__ == '__main__':
    main()
