I have looked on this forum and everything looks like what I have (I think). I have tried deleting and retyping the trouble line. I get these error messages: File "python", line 5
SyntaxError: invalid syntax
and from codecademy:
Oops, try again. Your code threw the following error: invalid syntax (python, line 5)
I expect to get a tranquil sea of O's.
board= for i in range(0,5): board.append(['O']* 5 def print_board(board): for row in board: print row print print_board(board)
