为什么我的player_turns（）不增加1？

Question

我正在研究用python编写的2人战舰游戏。我的player_turns（）使它在玩家1和玩家2之间交替。但是当你玩的时候它只停留在玩家1上，为什么会这样呢？另外，我注意到如果你找到了船的位置并开始一个新的游戏，那么这艘船就没有找到一个新的位置并且保持和上一次游戏相同的坐标。我怎样才能让坐标改变每场比赛？

from random import randint 

game_board = [] 
player_one = { 
    "name": "Player 1", 
    "wins": 0, 
    "lose": 0 
} 
player_two = { 
    "name": "Player 2", 
    "wins": 0, 
    "lose": 0 
}

在递增total_turns后，您需要使用return语句。

一旦return语句被执行，函数就退出了。
