Error message: “Make sure you print “Oops, that’s not even in the ocean.” if the user guesses a row or column that is off the board.”
Based on the code I wrote, it is not supposed to not work.
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: ")) range_col = len(board) - 1 for lst in board: range_row = len(lst) - 1 if ship_row == guess_row and guess_col == ship_col: print "Congratulations! You sank my battleship!" board[guess_row][guess_col] = "X" else: if guess_row not in range(range_row) \ or guess_col not in range(range_col): print "Oops, that's not even in the ocean" else: print "You missed my battleship!" board[guess_row][guess_col] = "X" print print_board(board)
Thanks for your help
