1、计算器

1. 案例介绍

本例利用 Python 开发一个可以进行简单的四则运算的图形化计算器,会用到 Tkinter 图形组件进行开发。主要知识点:Python Tkinter 界面编程;计算器逻辑运算实现。本例难度为初级,适合具有 Python 基础和 Tkinter 组件编程知识的用户学习。

2. 设计原理

要制作一个计算器,首先需要知道它由哪些部分组成。示意如下图所示。

从结构上来说,一个简单的图形界面,需要由界面组件、组件的事件监听器(响应各类事件的逻辑)和具体的事件处理逻辑组成。界面实现的主要工作是创建各个界面组件对象,对其进行初始化,以及控制各组件之间的层次关系和布局。

2、记事本

1. 案例介绍

tkinter 是 Python下面向 tk 的图形界面接口库,可以方便地进行图形界面设计和交互操作编程。tkinter 的优点是简单易用、与 Python 的结合度好。tkinter 在 Python 3.x 下默认集成,不需要额外的安装操作;不足之处为缺少合适的可视化界面设计工具,需要通过代码来完成窗口设计和元素布局。

本例采用的 Python 版本为 3.8,如果想在 python 2.x下使用 tkinter,请先进行安装。需要注意的是,不同 Python 版本下的 tkinter 使用方式可能略有不同,建议采用 Python3.x 版本。

本例难度为中级,适合具有 Python 基础和 Tkinter 组件编程知识的用户学习。

3、登录和注册

1. 案例介绍

本例设计一个用户登录和注册模块,使用 Tkinter 框架构建界面,主要用到画布、文本框、按钮等组件。涉及知识点:Python Tkinter 界面编程、pickle 数据存储。本例实现了基本的用户登录和注册互动界面,并提供用户信息存储和验证。

pickle 是 python 语言的一个标准模块,安装 python 后已包含 pickle 库,不需要单独再安装。pickle 模块实现了基本的数据序列化和反序列化。通过 pickle 模块的序列化操作能够将程序中运行的对象信息保存到文件中去,久存储;通过 pickle 模块的反序列化操作,能够从文件中创建上一次程序保存的对象。

本例难度为中级,适合具有 Python 基础和 Tkinter 组件编程知识的用户学习。

游戏开发

1、2048

1. 游戏简介

2048 是一款比较流行的数字游戏。游戏规则:每次可按上、下、左、右方向键滑动数字,每滑动一次,所有数字都会往滑动方向靠拢,同时在空白位置随机出现一个数字,相同数字在靠拢时会相加。不断叠加最终拼出 2048 这个数字算成功。

2048 最早于 2014年3月20日发行。原版 2048 首先在 GitHub 上发布,原作者是 Gabriele Cirulli,后被移植到各个平台。

本例难度为初级,适合具有 Python 基础和 Pygame 编程知识的用户学习。

2. 设计原理

这个游戏的本质是二维列表,就以 4*4 的二位列表来分析关键的逻辑以及实现。二维列表如下图:

所有的操作都是对这个二维列表的数据的操作。分为上下左右四个方向。先说向左的方向(如图)。

向左操作的结果如下图;当向左的方向是,所有的数据沿着水平方向向左跑。

水平说明操作的是二维列表的一行,而垂直操作的则是二位列表的一列。这样就可以将二维列表的操作变成遍历后对一维列表的操作。向左说明数据的优先考虑的位置是从左开始的。这样就确定了一维列表的遍历开始的位置。

上面第 2 个图共四行,每一个行都能得到一个列表。

list1[0,0,2,0]list2[0,4,2,0]list3[0,0,4,4]list4[2,0,2,0]

这样一来向左的方向就变成。从上到下获得每一行的列表,方向向左。参数(row,left)。

其他的三个方向在开始的时候记住是怎样获得以为列表的,等操作完才放回去这样就能实现了。

2、贪吃蛇

1. 案例介绍

贪吃蛇是一款经典的益智游戏,简单又耐玩。该游戏通过控制蛇头方向吃蛋,从而使得蛇变得越来越长。

通过上下左右方向键控制蛇的方向,寻找吃的东西,每吃一口就能得到一定的积分,而且蛇的身子会越吃越长,身子越长玩的难度就越大,不能碰墙,不能咬到自己的身体,更不能咬自己的尾巴,等到了一定的分数,就能过关,然后继续玩下一关。

本例难度为中级,适合具有 Python 基础和 Pygame 编程知识的用户学习。

2. 设计要点

游戏是基于 PyGame 框架制作的,程序核心逻辑如下:

游戏界面分辨率是 640*480,蛇和食物都是由 1 个或多个 20*20 像素的正方形块儿(为了方便,下文用点表示 20*20 像素的正方形块儿) 组成,这样共有 32*24 个点,使用 pygame.draw.rect 来绘制每一个点;

初始化时蛇的长度是 3,食物是 1 个点,蛇初始的移动的方向是右,用一个数组代表蛇,数组的每个元素是蛇每个点的坐标,因此数组的第一个坐标是蛇尾,最后一个坐标是蛇头;游戏开始后,根据蛇的当前移动方向,将蛇运动方向的前方的那个点 append 到蛇数组的末位,再把蛇尾去掉,蛇的坐标数组就相当于往前挪了一位;如果蛇吃到了食物,即蛇头的坐标等于食物的坐标,那么在第 2 点中蛇尾就不用去掉,就产生了蛇长度增加的效果;食物被吃掉后,随机在空的位置(不能与蛇的身体重合) 再生成一个;通过 PyGame 的 event 监控按键,改变蛇的方向,例如当蛇向右时,下一次改变方向只能向上或者向下;当蛇撞上自身或墙壁,游戏结束,蛇头装上自身,那么蛇坐标数组里就有和舌头坐标重复的数据,撞上墙壁则是蛇头坐标超过了边界,都很好判断;其他细节:做了个开始的欢迎界面;食物的颜色随机生成;吃到实物的时候有声音提示等。

3、俄罗斯方块

1. 案例介绍

俄罗斯方块是由 4 个小方块组成不同形状的板块,随机从屏幕上方落下,按方向键调整板块的位置和方向,在底部拼出完整的一行或几行。这些完整的横条会消失,给新落下来的板块腾出空间,并获得分数奖励。没有被消除掉的方块不断堆积,一旦堆到顶端,便告输,游戏结束。

本例难度为高级,适合具有 Python 进阶和 Pygame 编程技巧的用户学习。

2. 设计要点

边框――由 15*25 个空格组成,方块就落在这里面。

盒子――组成方块的其中小方块,是组成方块的基本单元。

方块――从边框顶掉下的东西,游戏者可以翻转和改变位置。每个方块由 4 个盒子组成。

形状――不同类型的方块。这里形状的名字被叫做 T, S, Z ,J, L, I , O。如下图所示:

模版――用一个列表存放形状被翻转后的所有可能样式。全部存放在变量里,变量名字如 S or J。

着陆――当一个方块到达边框的底部或接触到在其他的盒子话,就说这个方块着陆了。那样的话,另一个方块就会开始下落。

4、连连看

1. 案例介绍

连连看是一款曾经非常流行的小游戏。游戏规则:

  1. 点击选中两个相同的方块。

  2. 两个选中的方块之间连接线的折点不超过两个(接线由X轴和Y轴的平行线组成)。

  3. 每找出一对,它们就会自动消失。

  4. 连线不能从尚未消失的图案上经过。

  5. 把所有的图案全部消除即可获得胜利。

2. 设计思路

  1. 生成成对的图片元素。

  2. 将图片元素打乱排布。

  3. 定义什么才算 相连(两张图片的连线不多于3跟直线,或者说转角不超过2个)。

  4. 实现 相连 判断算法。

  5. 消除图片元素并判断是否消除完毕。

# -----------------------------------------'''#第三种,双直角连通双直角联通判定可分两步走:1. 在p1点周围4个方向寻找空格checkP2. 调用OneCornerLink(checkP, p2)3. 即遍历 p1 4 个方向的空格,使之成为 checkP,然后调用 OneCornerLink(checkP, p2)判定是否为真,如果为真则可以双直角连同,否则当所有的空格都遍历完而没有找到一个checkP使OneCornerLink(checkP, p2)为真,则两点不能连同具体代码:
