1 前言
在数字的世界里，古老的棋盘游戏焕发出崭新的活力，因为它们不再只属于人类玩家。本文将带您进入一个充满策略和智慧的领域，通过Python的神奇力量，将经典的井字棋游戏推向了新的高度。
这不再是单纯的人机对战，而是一场与AI智慧的较量。我们将使用tkinter库创建一个令人赞叹的游戏界面，其美观和交互性将让您身临其境。更令人兴奋的是，在这个看似简单的游戏中，隐藏着一个精心设计的AI算法，它将成为您的对手，挑战您的智力极限。
从界面的绘制到用户与AI的交互，再到AI算法的实现，本文将为您逐一揭示这些奥秘。您将亲手编写代码，让AI学会最佳的棋局选择，让游戏不再是孤独的战斗，而是与AI智慧共舞的快乐时光。
准备好迎接这个引人入胜的冒险了吗？让我们一起踏上这个富有挑战性和创造性的Python之旅，探索AI与人类之间的智力角逐！

2 代码分模块介绍
2.1 导入需要的库
分别是tkinter 、random
from tkinter import *
import tkinter.messagebox as msq
import random
2.2 定义全局变量
这里定义了窗体大小，窗体标题以及九个可落子位置的序号和变量值。
def __init__(self, master=None):
self.root = master # 定义内部变量root
self.root.title("井字棋")
self.root.geometry('%dx%d' % (600, 400)) # 设置窗口大小
self.panels = ["panel"]*10
self.count = 0
self.digits = [1, 2, 3, 4, 5, 6, 7, 8, 9]
self.mark = ""
self.btn_text1 = StringVar()
self.btn_text2 = StringVar()
self.btn_text3 = StringVar()
self.btn_text4 = StringVar()
self.btn_text5 = StringVar()
self.btn_text6 = StringVar()
self.btn_text7 = StringVar()
self.btn_text8 = StringVar()
self.btn_text9 = StringVar()
self.computerLetter = "O"
self.createPage()
2.2 定义玩家类
def read_name(self):
return [0,"玩家"]
def read_choose(self):
return "X"
2.3 定义页面类
利用gird对页面进行合理的分布，下子的方框实则是button，利用command对button进行动态改变
def createPage(self):
self.page = Frame(self.root) # 创建Frame
self.page.pack()
Label(self.page, text="{0},您选择的棋子是{1}，您为先手".format(self.read_name()[1], self.read_choose())).grid(row=0, stick=W, pady=10)
button1 = Button(self.page, textvariable=self.btn_text1, width=10, font=('Times 16 bold'), height=3, command=lambda:self.update_btn_text(1))
button1.grid(row=1, column=1)
button2 = Button(self.page, textvariable=self.btn_text2, width=10, height=3, font=('Times 16 bold'), command=lambda:self.update_btn_text(2))
button2.grid(row=1, column=2)
button3 = Button(self.page, textvariable=self.btn_text3, width=10, height=3, font=('Times 16 bold'), command=lambda:self.update_btn_text(3))
button3.grid(row=1, column=3)
button4 = Button(self.page, textvariable=self.btn_text4, width=10, height=3, font=('Times 16 bold'), command=lambda:self.update_btn_text(4))
button4.grid(row=2, column=1)
button5 = Button(self.page, textvariable=self.btn_text5, width=10, height=3, font=('Times 16 bold'), command=lambda:self.update_btn_text(5))
button5.grid(row=2, column=2)
button6 = Button(self.page, textvariable=self.btn_text6, width=10, height=3, font=('Times 16 bold'), command=lambda:self.update_btn_text(6))
button6.grid(row=2, column=3)
button7 = Button(self.page, textvariable=self.btn_text7, width=10, height=3, font=('Times 16 bold'), command=lambda:self.update_btn_text(7))
button7.grid(row=3, column=1)
button8 = Button(self.page, textvariable=self.btn_text8, width=10, height=3, font=('Times 16 bold'), command=lambda:self.update_btn_text(8))
button8.grid(row=3, column=2)
button9 = Button(self.page, textvariable=self.btn_text9, width=10, height=3, font=('Times 16 bold'), command=lambda:self.update_btn_text(9))
button9.grid(row=3, column=3)
