# Q1. Given
#
# - inputString, a string of zero or more lower case letters
# - replacement, a string of zero or more characters
#
# return a new string in which every vowel of inputString has been
# replaced with replacement.
#
# For this problem consider vowels to be a, e, i, o, and u.
#
# For example:
# >>> replaceVowels("hello", "z")
# "hzllz"
# >>> replaceVowels("hi", "aa")
# "haa"
# >>> replaceVowels("goodbye", "")
# "gdby"
#
def replaceVowels (inputString, replacement):
    vowels = "aeiou"
    if inputString == "":
        return ""
    elif inputString[0] in vowels:
        return replacement + replaceVowels(inputString[1:], replacement)
    else:
        return inputString[0] + replaceVowels(inputString[1:], replacement)

def testReplaceVowels():
    print(replaceVowels("hello", "z"))
    print(replaceVowels("hi", "aa"))
    print(replaceVowels("goodbye", ""))
    
# Q2. Given a list, print all the "contents" of the lists.  Here, "content"
# means all non-list items with in the list (maybe deeply nested within
# the list.
#
# For example,
# >>> printContents([1,2,'a'])
# 1
# 2
# a
#
# >>> printContents([1, [], 'a', [[[[3,4]]]], [[5],99]])
# 1
# a
# 3
# 4
# 5
# 99
#
# The function must be recursive but may also contain a loop.
#
# Solution outline:
# Iterate over the items of the list:
#   If an item is not a list, print it.
#   Otherwise, since recursively call this function on the item.
def printContents(inputList):
    for item in inputList:
        if type(item) == list:
            printContents(item)
        else:
            print(item)


def testPrintContents():
    printContents([1,2,'a'])
    printContents([1, [], 'a', [[[[3,4]]]], [[5],99]])
