Question

看来，当输入坐标（例如13 45）时，它总是会被“遗失”，我认为这是因为功能gamemode_one（）未链接到主要功能print_board（board）。船只的位置是随机生成的。以下是仅适用于初学者模式（1）的代码。

我还希望您能提供一些提示，以帮助在击中某艘船的坐标时如何对整个船进行遮罩？（船长5个字符）。

import random
from random import randint

board = []
board_size = 60

board_top = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "0"]

#creating the board
def print_board(board):
    boardHeader=[]
    boardHeader.extend(board_top*6)
    print('    ', end='')
    for i in range(1,7):
        print(str(i).rjust(20), end="")
    print()
    print('    ', end='')
    for i in boardHeader:
        print(str(i).rjust(2), end='')
    print()

    for x in range(20):
        board.append(["#"] * board_size)

    row = 0
    for i in range(len(board)):
       print (str(row + 1).rjust(2), ' ', end = "")
       for j in range(len(board[row])):
           print(board[row][j].rjust(2), end='')
       row +=1
       print()
    return board
print("Let's play Battleship game!")            
print_board(board)

#generate random row and column

Answer 1

您总是通过以下方式从gamemode_one()返回：

return (9,18)

没有随机性。

编辑后：

生成随机数后，您可以很容易地看到通过写入print(ship_row, ship_col)生成了正确的随机数。您将始终获得随机数。但是，您的board的大小为60x20，因此有1200个元素。因此，您的猜测输入等于随机数的概率约为0.1％，您将需要平均重复进行1200次猜测才能获得成功。

您的整个代码中也充满了冗余，未使用的部分，不必要的部分以及对我没有任何意义的内容。特别是您要比较的随机数是由ship_row = gamemode_one()[0]和ship_col = gamemode_one()[1]生成的。 gamemode_one将使用全局board的尺寸作为随机变量的限制。除开头的print_board外，永远不要使用其内容。

我认为您不了解局部和全局变量背后的概念。只要让board是所有函数都使用的全局变量，就不要通过函数参数传递它并返回它。
