RESTful Python
简介RESTful Python
RESTful Python是一种使用Python编程语言实现RESTful API的方法。下面是一些常用的Python库和框架，可以用来创建RESTful API:
-
Flask： Flask是一个轻量级的Python Web框架，可以用来创建RESTful API。它具有灵活、易于使用和快速开发的特点。
-
Django REST framework：Django REST framework是一个强大的Web框架，可以用来快速创建RESTful API。它提供了许多功能，例如认证、授权、序列化和视图等。
-
Falcon：Falcon是一个高性能的Python Web框架，可以用来创建RESTful API。它不仅仅是一个Web框架，还提供了许多中间件和扩展，可以帮助你快速构建高性能的API。
-
Pyramid：Pyramid是一个开源的Python Web框架，可以用来创建RESTful API。它支持多种模板语言、路由和中间件，可以帮助你快速开发复杂的Web应用程序和API。
以上是一些常用的Python库和框架，可以用来创建RESTful API。根据自己的需要和技能水平，选择一个适合自己的框架进行开发即可。
安装django rest framework
建立环境
python -m venv venv目录多了一个venv目录，可以看到里面的文件夹内容
激活venv环境
目录路径前面多（venv） 说明venv 环境激活
安装相应的python 包 django
pip install django 直接就安装完毕
pip install django
