Need to finish the tic tac toe game in python. Functions for Tic Tac Toe In Python are below

def erasTable (tab): ''' (list) -> None This function prepares the game table (array) by putting '-' in all the elements. It does not create a new array Preconditions: tab is a reference to an nxn array matrice n x n that contains '-', 'X' or 'O' ''' # to complete # returns nothing

def verifyWin(tab): '''(list) -> bool * Preconditions: tab is a reference to an nxn array that contains '-', 'X' or 'O' * Verify if there is a winner. * Look for 3 X's and O's in a row, column, and diagonal. * If we find one, we display the winner (the message "Player X has won" * or "Player O has won!") and returns True. * If there is a draw (verify it with the function testdraw), * display "It is a draw" and returns True. * If the game is not over, returns False. * The function call the functions testrows, testCols, testDiags * pour verifier s'il y a un gagnant. * Those functions returns the winner 'X' or 'O', or '-' if there is no winner. '''

# to complete return False # to change

def testLignes(tab): ''' (list) -> str * verify if there is a winning row. * Look for three 'X' or three 'O' in a row. * If they are found, the character 'X' or 'O' is returned, otherwise '-' is returned. * Preconditions: tab is a reference to an nxn array that contains '-', 'X' or 'O' '''

# to complete return '-' # to be modified so that it returns the winner, or '-' if there is no winner

def testCols(tab): ''' (list) -> str * verify a winning column. * look for three 'X' or three 'O' in a column. * If it is the case the character 'X' or 'O' is returned, otherwise '-' is returned. * Preconditions: tab is a reference to an nxn array that contains '-', 'X' or 'O' ''' # to complete return '-' #to be modified so that it returns the winner, or '-' if there is no winner

def testDiags(tab): ''' (list) -> str * Look for three 'X' or three 'O' in a diagonal. * If it is the case, the character 'X' or 'O' is returned * otherwise '-' is returned. * Preconditions: tab is a reference to an nxn array that contains '-', 'X' or 'O' '''

# to complete return '-' # #to be modified so that it returns the winner, or '-' if there is no winner

def testDraw(tab): ''' (list) -> bool * verify if there is a draw * check if all the array elements have X or O, not '-'. * If we do not find find any '-' in the array, return True. * If there is any '-', return false. * Preconditions: tab is a reference to an nxn array that contains '-', 'X' or 'O' ''' # to complete return False # to BE modiffied
