So using [guess_row - 1] as an index is necessary to return the correct board for already guessed spaces. However the error message says I need to use [guess_row] as an index.
There are a few topics on this already but none are very clear about what is going on. The console says I have it right when I use [guess_row][guess_col] as the indices, but the board it returns is completely incorrect. Am I doing something wrong here?
from random import randint board =  for x in range(0, 5): board.append(["O"] * 5) def print_board(board): for row in board: print " ".join(row) print_board(board) def random_row(board): return randint(0, len(board) - 1) def random_col(board): return randint(0, len(board) - 1) ship_row = random_row(board) ship_col = random_col(board) print ship_row print ship_col guess_row = int(raw_input("Guess Row:")) guess_col = int(raw_input("Guess Col:")) # Write your code below! if guess_row == ship_row and guess_col == ship_col: print "Congratulations! You sank my battleship!" else: print "You missed my battleship!" board[guess_row - 1][guess_col - 1] = "X" print_board(board)
