Good! I am creating the game Battleship and I found a problem creating the board.

Code:

board = []

for x in range(15):
    board.append(["O"] * 15)

def print_board(board):
    for row in board:
        print (" ").join(row)

And when I print the board give me this mistake:

  print (" ").join(row)
AttributeError: 'NoneType' object has no attribute 'join'

And I don’t understand what’s wrong... Someone can help me?

Probably the parenthesis sign in the command print should be:

for row in board:
  print(" ".join(row)) # -> aqui!!

After the change, the program prints:

O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O
O O O O O O O O O O O O O O O

  • had been the real problem!
