Question

我正在尝试制作一款简单的双人游戏，如经典的战舰。因此，我开始学习Python，我保持简单。我已经创建了一个5x5网格，我希望玩家（2）能够在船上的任何地方放置一个1x1的船。然后他们轮流猜测对方放置船的位置。

当我编译代码时，我在第61行"else: "上收到了缩进错误。我知道命中和未命中的“H”和“M”将重叠，因为我将它输出到同一个游戏板。

我想我需要帮助的是我的代码中的while循环。

import sys

#////////////////////////////Setting up board////////////////////////////////////
board = []

for x in range(5):
    board.append(["O"] * 5)

def print_board(board):
    for row in board:
        print " ".join(row)


#///////////////////////////Getting input//////////////////////////////////////////
def user_row():
    get_row = raw_input("Enter ship row between 1 and 5")
    #Not shure if this is the best way of checking that the input is an int
    if int(get_row) == False:
        print "You must enter an integer between 1 and 5"
        get_row = raw_input("Enter ship row...")
        if int(get_row) == False:
            sys.exit()

def user_col():
    get_col = raw_input("Enter ship col between 1 and 5")
    if int(get_col) == False:
        print "You must enter an integer between 1 and 5"
        get_col = raw_input("Enter ship col...")
        if int(get_col) == False:
            sys.exit()

#/////////////////////////Intro//////////////////////////////////////////////////////
print "Let's play Battleship!"
print "This is your ocean"
print_board(board)


#////////////////////////Placing ships//////////////////////////////////////////////
print "Player 1 your up!"
print "Player 2 look away!"
print "Place your ship..."

#Not shure if this will call the two functions chronologic and store them as index 0 and 1 in my array. That is what I want it to do
user1_ship = [user_row(), user_col()]

print_board(board)
print "Player 2 your up!"
print "Player 1 look away!"
print "Place your ship..."

user_2 = [user_row(), user_col()]


#///////////////////////guesswork?//////////////////////////////////////////////////
#Maybe while loops inside while loops is not the best way of running the code over and over until someone sinks the other persons ship
#What Im expecting is the first inside while loop to break the outer loop if the player hits the other players ship otherwise break itself. Likewise with the second inner loop.
while True:
    while True:
        print "Player 1 your turn"
        user1_guess = [user_row(), user_col()]
        if user1_guess == user2_ship:
            board[user1_guess[0]][user1_guess[1]] == "H"
            print "PLAYER 1 WINS!"
    break
        else:
            board[user1_guess[0]][user1_guess[1]] == "M"
            print "You missed"
            break
    while True:
        print "Player 2 your turn"
        user2_guess = [user_row(), user_col()]
        if user2_guess == user1_ship:
            board[user2_guess[0]][user2_guess[1]] == "H"
            print "PLAYER 2 WINS!"
    break
        else:
            board[user2_guess[0]][user2_guess[1]] == "M"
            print "You missed"
            break

你的缩进是不正确的......看看这个：

while True:
    while True:
        print "Player 1 your turn"
        user1_guess = [user_row(), user_col()]
        if user1_guess == user2_ship:
            board[user1_guess[0]][user1_guess[1]] == "H"
            print "PLAYER 1 WINS!"
    break

break语句必须与print语句具有相同的缩进，如下所示：

while True:
    while True:
        print "Player 1 your turn"
        user1_guess = [user_row(), user_col()]
        if user1_guess == user2_ship:
            board[user1_guess[0]][user1_guess[1]] == "H"
            print "PLAYER 1 WINS!"
            break
