为什么我的程序挂起

Question

from random import *

IQ = []
row1 = ["#", "#", "#"]
row2 = ["#", "#", "#"]
row3 = ["#", "#", "#"]
board = [row1, row2, row3]


def Display_Board():
    print(row1[0],"|", row1[1], "|", row1[2])
    print("----------")
    print(row2[0],"|", row2[1], "|", row2[2])
    print("----------")
    print(row3[0],"|", row3[1], "|", row3[2])

def Automated_Move(board):
    while True:
        RandomMove = randint(0,2)
        if board[RandomMove][RandomMove] == "#":
            board[RandomMove][RandomMove] = "O"
            break
        elif board[RandomMove][RandomMove] != "#":
            pass

while True:
    #print(IQ)
    Display_Board()
    Row = int(input("Row: ")) - 1
    Col = int(input("Col: ")) - 1
    if board[Row][Col] != "X" and board[Row][Col] != "O":
        board[Row][Col] = "X"
        IQ.append(Row)
        IQ.append(Col)
    elif board[Row][Col] == "X" or board[Row][Col] == "O":
        print("This is already Taken")
        pass

    Automated_Move(board)
    print("\n")

我正在尝试制作一个基于遗传算法的井字游戏，我不知道为什么它崩溃了。 我发现它在Automated_Move函数的循环中（如果有帮助的话）

您的主循环永无止境。 没有break ：

while True:
    #print(IQ)
    Display_Board()
    Row = int(input("Row: ")) - 1
    Col = int(input("Col: ")) - 1
    if board[Row][Col] != "X" and board[Row][Col] != "O":
        board[Row][Col] = "X"
        IQ.append(Row)
        IQ.append(Col)
    elif board[Row][Col] == "X" or board[Row][Col] == "O":
        print("This is already Taken")
        pass

    Automated_Move(board)
    print("\n")

同样，您的Automated_Move()的while循环迟早也会陷入永远的循环。

def Automated_Move(board):
    while True:
        RandomMove = randint(0,2)
        if board[RandomMove][RandomMove] == "#":
            board[RandomMove][RandomMove] = "O"
            break
        elif board[RandomMove][RandomMove] != "#":
            pass

仅在board存在'#'元素时（将元素更改为O ），此循环才会中断。 经过几次迭代后， board所有（对角线）元素都将为'O' ，因此循环将永远不会退出。

一种可能的解决方案是将主循环修改为：

if any(['#' in r for r in board]):
    Automated_Move(board)
else:
    break
