# Lecture 4, Problem 11

##Define a function isVowel2(char) that returns True if char is a vowel
##('a', 'e', 'i', 'o', or 'u'), and False otherwise. You can assume that
##char is a single letter of any case (ie, 'A' and 'a' are both valid).
##
##This function is similar to the previous problem - but this time,
##do use the keyword in. Your function should take in a single string
##and return a boolean.

def isVowel2(char):
    '''
    char: a single letter of any case

    returns: True if char is a vowel and False otherwise.
    '''

    vowels = ["a", "A", "e", "E", "i", "I", "o", "O", "u", "U"]
    return (char in vowels)

    
# Test cases
print str(isVowel("a"))
print str(isVowel("A"))
print str(isVowel("z"))
print str(isVowel("t"))
