基于flask实现五子棋小游戏

时间:2022-10-30 15:36:00

本文实例为大家分享了基于flask实现五子棋小游戏的具体代码,供大家参考,具体内容如下

前言

首先说明一下,本人方向是java后端,只因老师布置了一个作业,要用flask来做一个五子棋,没办法被逼上梁山,程序不太美观,但是应付作业还是够了的。

废话不多说,下面开锤!

首先整个程序是一个web应用,前端html+css+javaScript(有用到jquery)(基本都是现学的,所以程序很多注释也很丑),后端用的flask框架。

准备工作

**1.**python环境、安装flask

**2.**导入需要用到的包

?
1
2
pip install flask_cors
pip install flask_sqlalchemy

**3.**创建一个flask项目,并将一下代码复制运行
