# 1. Super vowels¶

Implement super_vowels function which takes a string as an argument and returns a modified version of that string. In the return value of super_vowels, all vowels should be in upper case whereas all consonants should be in lower case. The vowels are listed in the VOWELS variable.

In [ ]:
VOWELS = ['a', 'e', 'i', 'o', 'u']

In [ ]:
# Your implementation here

In [ ]:
assert super_vowels('hi wassup!') == 'hI wAssUp!'
assert super_vowels('HOw aRE You?') == 'hOw ArE yOU?'


# 2. Playing board¶

Implement get_playing_board function which takes an integer as an argument. The function should return a string which resemples a playing board (e.g. a chess board). The board should contain as many rows and columns as requested by the interger argument. See the cell below for examples of desired behavior.

In [ ]:
# Your implementation here

In [ ]:
board_of_5 = (
' * * \n'
'* * *\n'
' * * \n'
'* * *\n'
' * * \n'
)

board_of_10 = (
' * * * * *\n'
'* * * * * \n'
' * * * * *\n'
'* * * * * \n'
' * * * * *\n'
'* * * * * \n'
' * * * * *\n'
'* * * * * \n'
' * * * * *\n'
'* * * * * \n'
)

assert get_playing_board(5) == board_of_5
assert get_playing_board(10) == board_of_10

print(get_playing_board(50))
