# Format Board

In this assignment you'll be formatting a simple Tic Tac Toe board:

``````O  |  O  |  X
--------------
X  |  X  |  O
--------------
O  |  X  |  O
``````

The information of the rows of the board will be kept as strings. Example (considering the board above):

``````first_row = 'OOX'
second_row = 'XXO'
third_row = 'OXO'
``````

The function that you need to write is `format_tic_tac_toe_board` that just receives those three rows. It will return the board with those rows filled in correctly from the row information.

Example:

``````first_row = 'OOX'
second_row = 'XXO'
third_row = 'OXO'

board = format_tic_tac_toe_board(first_row, second_row, third_row)

print(board)  # Result below:
O  |  O  |  X
--------------
X  |  X  |  O
--------------
O  |  X  |  O
``````

Hint: String formatting (the `format` method) will be really important for this assignment

### Test Cases

test format empty board -

``````def test_format_empty_board():
"""
This is the board used in this test:
X  |  O  |  -
--------------
O  |  -  |  -
--------------
O  |  -  |  X
"""
first_row = 'XO-'
second_row = 'O--'
third_row = 'O-X'
expected_board = """
X  |  O  |  -
--------------
O  |  -  |  -
--------------
O  |  -  |  X
"""
board = format_tic_tac_toe_board(first_row, second_row, third_row)

assert board == expected_board
``````

test format full board -

``````def test_format_full_board():
"""
This is the board used in this test:
X  |  O  |  X
--------------
O  |  X  |  O
--------------
O  |  O  |  X
"""
first_row = 'XOX'
second_row = 'OXO'
third_row = 'OOX'
expected_board = """
X  |  O  |  X
--------------
O  |  X  |  O
--------------
O  |  O  |  X
"""
board = format_tic_tac_toe_board(first_row, second_row, third_row)

assert board == expected_board
