In the pencil-and-paper game, Tic-tac-toe, 2 players take turns to mark 'X' and 'O' on a board of 3x3 squares. The player who succeeds in marking 3 successive 'X' or 'O' in vertical, horizontal or diagonal stripe wins the game. Write a function that determines the outcome of a tic-tac-toe game.

Examples

>>> tictactoe([('X', ' ', 'O'), 
               (' ', 'O', 'O'), 
               ('X', 'X', 'X') ])
"'X' wins (horizontal)."
>>> tictactoe([('X', 'O', 'X'), 
...            ('O', 'X', 'O'), 
...            ('O', 'X', 'O') ])
'Draw.'
>>> tictactoe([('X', 'O', 'O'), 
...            ('X', 'O', ' '), 
...            ('O', 'X', ' ') ])
"'O' wins (diagonal)."
>>> tictactoe([('X', 'O', 'X'), 
...            ('O', 'O', 'X'), 
...            ('O', 'X', 'X') ])
"'X' wins (vertical)."



def tictactoe(moves):
    for r in range(len(moves)):
        for c in range(len(moves[r])):      
            if moves[0][c]==moves[1][c]==moves[2][c]:
                a="'%s' wins (%s)."%((moves[0][c]),'vertical')
            elif moves[r][0]==moves[r][1]==moves[r][2]:
                a="'%s' wins (%s)."%((moves[r][0]),'horizontal')
            elif moves[0][0]==moves[1][1]==moves[2][2]:
                a="'%s' wins (%s)."%((moves[0][0]),'diagonal')
            elif moves[0][2]==moves[1][1]==moves[2][0]:
                a="'%s' wins (%s)."%((moves[0][2]),'diagonal')
            else:
                a='Draw.'
    print(a)

I wrote a code like this and my range is not working(i think). because, it takes the value for r and c as 3, not 0,1,2,3. So, please anyone can help me with this ?
Thank you

Add a few print statements to see what's going on

def tictactoe(moves):
    for r in range(len(moves)):
        for c in range(len(moves[r])):
            print("(r, c) =", (r, c))
            if moves[0][c]==moves[1][c]==moves[2][c]:
                a="'%s' wins (%s)."%((moves[0][c]),'vertical')
            elif moves[r][0]==moves[r][1]==moves[r][2]:
                a="'%s' wins (%s)."%((moves[r][0]),'horizontal')
            elif moves[0][0]==moves[1][1]==moves[2][2]:
                a="'%s' wins (%s)."%((moves[0][0]),'diagonal')
            elif moves[0][2]==moves[1][1]==moves[2][0]:
                a="'%s' wins (%s)."%((moves[0][2]),'diagonal')
            else:
                a='Draw.'
            print("currently, a =", repr(a))
    print(a)
