PyMonad 项目教程

pymonadPyMonad implements data structures typically available in pure functional or functional first programming languages like Haskell and F#. Included are Monad and Monoid data types with several common monads included – such as Maybe and State – as well as some useful tools such as the @curry decorator for defining curried functions. PyMonad 2.x.x represents an almost complete re-write of the library with a simpler, more consistent interface as well as type annotations to help ensure correct usage.项目地址:https://gitcode.com/gh_mirrors/py/pymonad

1. 项目的目录结构及介绍

PyMonad 项目的目录结构如下：

pymonad/


├── LICENSE


├── README.md


├── pymonad/


│   ├── __init__.py


│   ├── _compatibility.py


│   ├── _decorators.py


│   ├── _either.py


│   ├── _maybe.py


│   ├── _monoid.py


│   ├── _reader.py


│   ├── _state.py


│   ├── _tools.py


│   ├── _writer.py


│   └── examples/


│       ├── __init__.py


│       ├── example1.py


│       ├── example2.py


│       └── ...


├── setup.py


└── tests/


    ├── __init__.py


    ├── test_compatibility.py


    ├── test_decorators.py


    ├── test_either.py


    ├── test_maybe.py


    ├── test_monoid.py


    ├── test_reader.py


    ├── test_state.py


    ├── test_tools.py


    ├── test_writer.py


    └── ...

目录介绍：

pymonad/: 项目的主要代码目录。
__init__.py: 初始化文件，使目录成为一个 Python 包。_compatibility.py: 兼容性模块。_decorators.py: 装饰器模块。_either.py: Either 类型模块。_maybe.py: Maybe 类型模块。_monoid.py: Monoid 类型模块。_reader.py: Reader 类型模块。_state.py: State 类型模块。_tools.py: 工具模块。_writer.py: Writer 类型模块。examples/: 示例代码目录。 setup.py: 安装脚本。tests/: 测试代码目录。

2. 项目的启动文件介绍

PyMonad 项目没有明确的启动文件，因为它是一个库，而不是一个可执行的应用程序。用户可以根据需要导入和使用 pymonad 包中的模块。

3. 项目的配置文件介绍

PyMonad 项目没有传统的配置文件，因为它主要是一个功能库。用户在使用时，直接导入所需的模块并调用其中的函数或类即可。

例如：

from pymonad.maybe import Just, Nothing


 


result = Just(10).map(lambda x: x * 2)


print(result)  # 输出: Just(20)

以上是 PyMonad 项目的基本教程，涵盖了项目的目录结构、启动文件和配置文件的介绍。希望对您有所帮助！
