====== 第四十二章：项目结构 ======

===== 本章目标 =====

完成本章学习后，你将能够：
  * 组织Python项目结构
  * 编写配置文件
  * 管理依赖
  * 发布项目到PyPI

===== 项目结构 =====

<code>
my_project/
├── src/
│   └── my_package/
│       ├── __init__.py
│       ├── module1.py
│       └── module2.py
├── tests/
│   ├── __init__.py
│   └── test_module1.py
├── docs/
├── .gitignore
├── LICENSE
├── README.md
├── pyproject.toml
└── requirements.txt
</code>

===== pyproject.toml =====

<code>
[build-system]
requires = ["setuptools>=61.0", "wheel"]
build-backend = "setuptools.build_meta"

[project]
name = "my_project"
version = "1.0.0"
description = "A sample project"
readme = "README.md"
requires-python = ">=3.8"
license = {text = "MIT"}
authors = [
    {name = "Author", email = "author@example.com"}
]
classifiers = [
    "Development Status :: 4 - Beta",
    "Intended Audience :: Developers",
    "License :: OSI Approved :: MIT License",
    "Programming Language :: Python :: 3",
]
dependencies = [
    "requests>=2.0",
    "numpy>=1.20",
]

[project.optional-dependencies]
dev = ["pytest", "black", "flake8", "mypy"]
</code>

===== 本章练习 =====

1. 创建规范的项目结构
2. 配置CI/CD
3. 发布到PyPI
