[程式/Python] 小遊戲 - BattleShip Code分享

剛剛在Codecademy完成了BattleShip的練習，原本打算改成2P，不過我先把它改成Python34的格式再加入重新開始和結束的選項。老實說，這遊戲真的不太好玩，編碼如下：

from random import randint

#function for print out the board
def print_board(board):
    for row in board:
        print (" ".join(row))

#variable for restart
re=1

while (re==1):
    #generate a game board
    board = []
    for row in range(5):
        board.append(["O"]*5)

    ship_row = randint(0,len(board)-1)
    ship_col = randint(0,len(board[0])-1)

    print ("Battle Ship!")
    print_board(board)

    #for debug, del it after finish
    print ("(", ship_row, ",", ship_col, ")")

    #give 4 turns to guess
    for turn in range(4):
        print ()
        print ("Turn ",turn+1)
        guess_row = int(input("Guess Row:"))
        guess_col = int(input("Guess Col:"))

        #different result according to the guess 
        if guess_row == ship_row and guess_col == ship_col:
            board[guess_row][guess_col] = "W"
            print ()
            print ("Congratulations! You sunk my battleship!")
            print_board(board)
            break
        else:
            print ()
            if guess_row not in range(5) or guess_col not in range(5):
                print ("Oops, that's not even in the ocean.")
            elif board[guess_row][guess_col] == "X":
                print ("You guessed that one already.")
            else:
                board[guess_row][guess_col] = "X"
                print ("You missed my battleship!")
            print_board(board)
            if turn == 3:
                print ("Gome Over")
    print ()

    #variable for asking restart
    res=1
    while(res==1):
        response = input("Restart(Y/N)? ")
        print ()
        response = response.upper()
        if response == "Y":
            res=0
        elif response == "N":
            res=0
            re=0
        else:
            print ("Invalid Input")
            print ()

    print ()
    print ()
    print ()

raise SystemExit("See You!")

當中加入了while loop和raise SystemExit()來作重新開始和結束遊戲的選擇。
