试图用Python

Question

我是Python的新手，我正在开发Connect Four游戏。我能够初始化电路板，自己动作，让计算机移动。但是，我知道必须有一种更好的“放置我的作品”的方式，而不是我拥有的大量IF语句。此外，我不确定如何接近实际检查游戏是否“赢得”或抽出的逻辑。

这是我的代码：

import random

board = [["." for x in range(7)] for x in range(6)]
symbol = ""

def boardLogic(pick, user):
    if user == "user":
        symbol = "0"
    else:
        symbol = "X"
    if board[0][pick] != ".":
        if board[1][pick] != ".":
            if board[2][pick] != ".":
                if board[3][pick] != ".":
                    if board[4][pick] != ".":
                        if board[5][pick] != ".":
                            if board[6][pick] != ".":
                                print("That column is full.")
                            else:
                                board[6][pick] = symbol
                        else:
                            board[5][pick] = symbol
                    else:
                        board[4][pick] = symbol
                else:
                    board[3][pick] = symbol
            else:
                board[2][pick] = symbol
        else:
            board[1][pick] = symbol
    else:
        board[0][pick] = symbol

def printBoard():
    for row in board:
        for val in row:
            print '{:4}'.format(val),
        print

won = False
while not won:
    printBoard()

    #pick a column
    #ADD FUNCTIONALITY TO DISALLOW A FULL COLUMN FROM BEING ENTERED
    while True:
        try:
            yourPick = int(raw_input('Pick a column 0 - 6: '))
        except ValueError: # just catch the exceptions you know!
            print 'That\'s not a number!'
        else:
            if 0 <= yourPick < 6: # this is faster
                break
            else:
                print 'Out of range. Try again'
    print(yourPick)
    #column logic
    boardLogic(yourPick, "user")

    #opponent randomly picks a column
    theirPick = random.randint(0, 6)
    print(theirPick)
    #column logic
    boardLogic(theirPick, "notUser")

    #check win conditions
    #won = True
