Python:连接 4

Question

我需要询问用户想要多少行和多少列，以便我的游戏可以处理任何大小的棋盘，但我不知道如何更改我的代码。这是我的用于 6x7 板的 connect 4 代码。

import random

def winner(board):
    """This function accepts the Connect 4 board as a parameter.
    If there is no winner, the function will return the empty string "".
    If the user has won, it will return 'X', and if the computer has
    won it will return 'O'."""

    # Check rows for winner
    for row in range(6):
        for col in range(3):
            if (board[row][col] == board[row][col + 1] == board[row][col + 2] ==\
                board[row][col + 3]) and (board[row][col] != " "):
                return board[row][col]

import sys

if sys.hexversion < 0x3000000:
    inp = raw_input
else:
    inp = input

def get_int(prompt):
    while True:
        try:
            return int(inp(prompt))
        except ValueError:
            pass

HEIGHT = get_int('How many rows? ')
WIDTH  = get_int('How many columns? ')

您现在可以在板范围范围内替换这些常量来调整板尺寸。
