Excuse me, I am stuck in this exercise. I know the code written by me doesn't meet the request but I have no idea about how to improve. I have read other's question but I more want to get some advice about my personal case.
Especially, when I guessed 4 times and don't guess the right position, my program couldn't print "Game Over". How can I rewrite my program?
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 # Everything from here on should go in your for loop! # Be sure to indent four spaces! for turn in range(4): if turn < 4: 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!" 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 "Turn", turn + 1 else: if turn == 3: print "Game Over"
