如何使用隨機重復選擇

Question

所以我正在嘗試制作一個井字游戲，您可以在其中與計算機對戰。 因為我不知道如何為計算機使用 AI 以便它可以做出決定，所以我選擇讓它使用隨機選擇。 因為它需要在多個回合中做出多項選擇，所以我想弄清楚如何擁有“選擇”變量循環，因此每次游戲循環時它都會做出不同的隨機選擇。 這是代碼。

import random

# Define the screen
screen = turtle.Screen()
screen.setup(width=300, height=300)

# Define the turtle
t = turtle.Turtle()
t.speed(0)

error = "Move already made, you lost a turn"

moves = ["top left", "top mid", "top right", "mid left", "mid mid", "mid right", "bot left", "bot mid", "bot right"]

如果您每次運行都想要不同的值，請將“random.seed()”放在程序的頂部。 有關解釋，請參閱隨機模塊文檔。

Answer 2

您的問題似乎是您不知道如何讓用戶和計算機交替輪流。 一種解決方案是在用戶移動事件處理程序中檢查用戶是否進行了有效的移動，如果是，並且還有移動，則告訴計算機進行移動。 我在下面使用了這種方法並在此過程中簡化了您的代碼：

from turtle import Screen, Turtle
from random import choice

moves = [ \
    'top left', 'top mid', 'top right', \
    'mid left', 'mid mid', 'mid right', \
    'bot left', 'bot mid', 'bot right', \
]

def makex(x, y):
    t.goto(x, y)

    t.pendown()
    t.left(45)
    t.forward(30)
    t.right(180)
    t.pendown()
    t.forward(60)

    t.penup()
    t.right(180)
    t.forward(30)
    t.right(90)
    t.forward(30)
    t.right(180)

    t.pendown()
    t.forward(60)

    t.penup()
    t.setheading(0)

def makeo(x, y):
    t.goto(x, y)

    t.right(90)
    t.forward(30)
    t.left(90)

    t.pendown()
    t.circle(30)

    t.penup()
    t.setheading(0)

def user(x, y):
    valid_move = False

    if moves:
        # Top row
        if 50 < y < 150:

還有更多的代碼簡化可以完成，但在這一點上是不值得的。 您的下一個障礙是添加評分邏輯，以確定任一玩家是否獲勝或是否已達到平局。
