第四十二章：项目结构

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

├── src/
│   └── my_package/
│       ├── __init__.py
│       ├── module1.py
│       └── module2.py
├── tests/
│   ├── __init__.py
│   └── test_module1.py

[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"]

1. 创建规范的项目结构 2. 配置CI/CD 3. 发布到PyPI
