用Python写了一个上课点名系统(附源码)(自制考勤系统)(python考勤管理系统)

今天刷到了一个这样的短视频,我寻思我是不是也可以写一个类似的上课点名程序,想法经不起等待,说写就写~

用Python写了一个上课点名系统(附源码)(自制考勤系统)(python考勤管理系统)一.准备工作

私信小编01即可获取大量python学习资源

1.Tkinter

Tkinter 是 Python 内置的 TK GUI 工具集。TK 是 Tcl 语言的原生 GUI 库。作为 python 的图形设计工具,它所使用的 Tcl 语言环境已经完全嵌入到了 python 解释器中。

我们使用Tkinter开发GUI界面。

2.PIL

PIL(Python Image Library)库是Python语言的第三方库,需要通过pip工具安装。安装PIL库的方法如下,需要注意,安装库的名字是pillow。

PIL库支持图像储存、显示和处理,他能够处理几乎所有图片格式,可以完成对图像的缩放、剪裁、叠加以及向图像添加线条、图像和文字等操作。

使用PIL中的Image,ImageTk处理、引入一张图片,可以使用下面代码安装一下。

pip install pillow

二.预览1.启动用Python写了一个上课点名系统(附源码)(自制考勤系统)(python考勤管理系统)

双击打开后,进入软件主界面,所有功能一目了然。程序会自动识别软件目录下的names.txt,将里面的名字导入。

2.开始点名-顺序点名用Python写了一个上课点名系统(附源码)(自制考勤系统)(python考勤管理系统)

选择顺序点名后,点击开始,屏幕上就开始滚动出现人名,人名出现的概率是相同的,点击停止,人名就停止滚动,点名结束。

3.开始点名-随机点名用Python写了一个上课点名系统(附源码)(自制考勤系统)(python考勤管理系统)

点击随机点名,程序就会进行随机点名,人名出现的概率是随机的。

4.手动加载人名单用Python写了一个上课点名系统(附源码)(自制考勤系统)(python考勤管理系统)

可以自己手动选择人名单,前提是人名单格式为txt,且每个名字占一行。

5.开始点名-顺序点名-Pyqt5版本用Python写了一个上课点名系统(附源码)(自制考勤系统)(python考勤管理系统)

用Pyqt5也写了一个版本,实现逻辑与TK版本相同,界面可能更好看了一些,但是文件大了许多,大家可以在后面总结部分自取。

三.思路1.整体实现思路用Python写了一个上课点名系统(附源码)(自制考勤系统)(python考勤管理系统)2.点名实现思路用Python写了一个上课点名系统(附源码)(自制考勤系统)(python考勤管理系统)四.源代码point_names-GUI.py(主程序GUI)

五.总结

本次使用Tkinter开发了一款上课点名程序,此程序可以用于点名、抽奖…代码不到200行,程序简单又实用,主要有以下六个亮点:

1.两种模式:

  • 顺序点名
  • 随机点名

2.自动识别人名单

3.支持手动导入人名单

4.人名单导入校验

5.人名显示位置自动矫正

6.最多显示五个大字
