保存数据的最佳方法 [英] Best method of saving data

问题描述

我开设了一个课程，我想在其中跟踪学生的统计数据.我打算稍后制作一个 GUI 来操作这些数据.

I've made a class in which I want to keep track of stats of students. I intend to make a GUI later to manipulate this data.

我的主要问题是:保存和以后检索这些数据的最佳方法是什么?

My main question is: what is the best way to save and later retrieve this data?

我读过关于 pickle 和 JSON 的文章，但我并不真正了解它们是如何工作的(尤其是关于它们如何保存数据，例如采用哪种格式和位置).

I've read about pickle and JSON, but I don't really get how they work (especially about how they save the data, like in which format and where).

推荐答案

对于持久数据(存储有关学生的信息)，数据库是一个不错的选择.正如已经提到的，Python 附带了 Sqlite3，它通常足够好，至少用于开发目的.

For persistent data (storing info about students), a database is a good choice. As already mentioned, Python comes shipped with Sqlite3 which is often good enough, for development purposes at least.

将 Sqlite 引入 Python 很容易 - 只需在源代码文件中导入库并打开与数据库的连接.请参阅 python 文档.

Introducing Sqlite to Python is easy - just import the library in your source code file and open a connection to your database. Refer to the python documentation.

编辑:发现一个关于 Python + Sqlite 的新教程，看起来似乎不错.

EDIT: Found a new tutorial about Python + Sqlite that seems good.
