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。但是当你玩它只停留在玩家1上时，为什么会这样呢？

此外，我注意到如果您找到了该船的位置并开始新游戏，则该船找不到新位置并保持与上次游戏相同的坐标。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
}

# Building our 5 x 5 board
def build_game_board(board):
    for item in range(5):
        board.append(["O"] * 5)

def show_board(board):
    print("Find and sink the ship!")
    for row in board:
        print(" ".join(row))

# Defining ships locations
def load_game(board):
    print("WELCOME TO BATTLESHIP!")
    print("START")
    del board[:]
    build_game_board(board)
    show_board(board)
    ship_col = randint(1, len(board))
    ship_row = randint(1, len(board[0]))
    return {
        'ship_col': ship_col,
        'ship_row': ship_row,
    }

ship_points = load_game(game_board)

# Players will alternate turns.
def player_turns():
    total_turns = 0
    if total_turns % 2 == 0:
        return player_one
        total_turns += 1

    else:
        return player_two

# Allows new game to start

    answer = input("Would you like to play again? ")
    if answer == "yes" or answer == "y":
        total_turns = 0

            break
    match = guess_row == ship_row - 1 and guess_col == ship_col - 1
    not_on_game_board = (guess_row < 0 or guess_row > 4) or (guess_col < 0 or guess_col > 4)

    if match:
        player["wins"] += 1
        print("Congratulations! You sunk my battleship!")
        print("Thanks for playing!")
        play_again()

    elif not match:
        if not_on_game_board:
            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!")

在递增Public Class Form1 Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load ' Configuring for Background Workers Control.CheckForIllegalCrossThreadCalls = False Dim MyList As New List(Of String) For a As Integer = 0 To 100 MyList.Add(CStr(a)) Next End Sub Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click Dim bgw As New System.ComponentModel.BackgroundWorker bgw.WorkerReportsProgress = True bgw.WorkerSupportsCancellation = True AddHandler bgw.DoWork, AddressOf bgw_DoWork ' I create a BackgroundWorker here rather than add one in the toolbox so that I can specify the Handler and use different Handler routines for different part of a large program.

执行return语句后，退出该函数。

为什么我的player_turns（）不会增加1？
