poetry 是一个包管理和打包的工具。
在Pytho 中，对于初学者来说，打包系统和依赖管理是非常复杂和难懂的。即使对于经验丰富的开发者，一个项目总是要同时创建多个文件：`setup.py`,`requiremets.txt`,`setup.cfg`,`MANIFEST.i`，还有最新的`Pipfile`。
基于此，poetry 将所有的配置都放置在一个toml 文件中，这些配置包括：依赖管理、构建、打包、发布。
poetry 的灵感来自于其他语言的一些工具：composer(PHP) 和cargo(Rust)。
配置poetry 的项目配置文件是pyproject.toml，一个简单的示例文件如下：
