Sorry for inappropriate topic
It's not an actual question, but some offer for guys who are trying to improve their code.
After losing a game, everyone wants to know the real ship location, as well as see the ship being marked on the board after you sunk it.
I am attaching the final code of this extension below, but first try to handle with it by yourself:)
from random import randint board =  for x in range(5): board.append(["O"] * 5) def print_board(board): for row in board: print " ".join(row) print "Let's play Battleship!" 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 for turn in range(4): print "Turn: ", turn + 1 guess_row = int(raw_input("Guess Row:")) guess_col = int(raw_input("Guess Col:")) if guess_row == ship_row and guess_col == ship_col: print "Congratulations! You sunk my battleship!" board[ship_row][ship_col] = "*" print_board(board) break else: if (guess_row < 0 or guess_row > 4) or (guess_col < 0 or guess_col > 4): print "Oops, that's not even in the ocean." elif(board[guess_row][guess_col] == "X"): print "You guessed that one already." else: print "You missed my battleship!" board[guess_row][guess_col] = "X" print_board(board) print "\n\n\n" if turn == 3: print 'Game over!' print 'Here is the actual ship location:' board[ship_row][ship_col] = "*" print_board(board)
