当玩家圈数=6时，程序退出。Python战舰

Question

我在用python做一个2人的战舰游戏。我已经这样做了，使每个'游戏'允许总共6个回合（3从每个球员），然后会出现一条消息说'的数量已结束'。你知道吗

一旦发生这种情况，他们将被要求再次发挥。如果他们回答“是”或“是”，游戏应该重新加载。然而，它没有。板加载，但程序然后退出。我相信问题出在play\u again（）函数上，但我不太确定它是什么。你知道吗

我想让玩家们可以玩任意多的游戏，直到他们决定回答“不”或“不”。我该如何实施这一点？你知道吗

Answer 1

问题是您的play_again()调用在接收到“Y”作为答案时，会加载电路板，但随后简单地返回。哪里？好吧，它是从main()中的for循环调用的。不幸的是，这是for循环的最后一次迭代，因此循环结束，程序退出。你知道吗

你应该在for循环上加一个循环：

while True:
    for turns in range(6):
       ...

Answer 2

尝试修改main：

turns = 0
while turns < 6:
    # Process turn...
    if turns == 5:
        # Show endgame board
        if play_again():
            turns = -1
    turns += 1

在正输入上返回{}，否则返回{}。你知道吗

Answer 3

当我在play\u again（）函数中向main添加一个调用时，它也对我起了作用：

# Allows new game to start
def play_again():

    positive = ["yes", "y"] 
    negative = ["no", "n"]

    global ship_points

    while True:
        answer = input("Play again? [Y(es) / N(o)]: ").lower().strip()
        if answer in positive:
            ship_points = load_game(game_board)
            main()
            break

        elif answer in negative:   
            print("Thanks for playing!")
            exit()
