Python實現四個經典小游戲的示例分析

本篇文章給大家分享的是有關Python實現四個經典小游戲的示例分析，小編覺得挺實用的，因此分享給大家學習，希望大家閱讀完這篇文章后可以有所收獲，話不多說，跟著小編一起來看看吧。

 一、效果展示

1、俄羅斯方塊

這個應該是玩起來最最簡單的了…

2、掃雷

運氣好，點了四下都沒踩雷哈哈…

3、五子棋

我是菜雞，玩不贏電腦人…

4、貪吃蛇

害，這個是最驚心動魄的，為了我的小心臟，不玩了不玩了…

女朋友：你就是借機在玩游戲，逮到了

啊這…

那我不吹牛逼了，我們來敲代碼吧~

二、代碼展示

1、俄羅斯方塊

方塊部分

這部分代碼單獨保存py文件，這里我命名為 blocks.py

方塊形狀的設計，一開始我是做成 4 × 4，長寬最長都是4的話旋轉的時候就不考慮怎么轉了，就是從一個圖形替換成另一個。

要實現這個功能，只要固定左上角的坐標就可以了。
