Readme in English

This is rewritten of original project 500 Lines or Less with improvements in the following aspects:

• Code written in PY2 are rewritten in PY3
• Remove some outdated content (e.g CGI) and replace with newer mechanism. For example, HTTP processing pipeline are introduced instead of CGI
• Written in a step-by-step manner, showing actual code for each step, so we can see how to make progress
• Some projects are developed in a test-driven (TDD) manner

Project relatived articles are published at My blog, in Chinese language.

How to Use

To run the program code, you need

• Python3. Any version higher than Python3.6 should work (however not verified). The development environment is Python3.8.

Code of each project is in a separated directory, naming after the original project. Some whitespace and - character are replaced with _ for the sake of references in code. Each step has also its own sub-directory.

To run a projects written in Python: open main.py, find the entry point for the project of interest, uncomment it and run.

本项目试图以更加现代化的方式重写 500 Lines or Less 项目，并在以下方面有所改进：

• 将基于 PY2 的项目改写为基于 PY3
• 删除部分过时的内容，用更适合现实的机制代替。例如，CGI 被 HTTP 处理管线替代
• 用循序渐进的方式编写代码，展示每个具体步骤，让读者能够更好地理解
• 部分项目采用测试驱动（TDD）的方式开发。

要运行程序代码，需要

• Python3。理论上任何高于 Python3.6 的版本均可（但未验证）。实际开发环境是 Python3.8

各个项目分别放在不同的目录下，命名方式遵照原先的名称，为了方便引用，部分空格或 - 用 _ 替代。对于使用迭代式开发的项目，每个步骤放在单独的目录下。

对于用 Python 实现的项目，请访问 main.py， 找到特定的项目以及步骤编号，取消注释并运行。
