1.2 可以运行在最新版本的Python、Jython、Android上。

1.3 其主要作用是以尽可能少的操作将Web服务器与Python代码连接。

1.4 是 CGI 的优秀替代品，并且是创建 Python Web 应用程序的良好基础。

2 环境：

=====

华为笔记本电脑，深度deepin-linux操作系统，python3.8，微软vscode编辑器，谷歌浏览器。

3 官网：

=====

安装
pip install CherryPy
#本机安装
#sudo pip3.8 install CherryPy   #有点慢，放弃
sudo pip3.8 install -i https://mirrors.aliyun.com/pypi/simple CherryPy #超快

5 hello world：

5.1 方法一，代码：

import cherrypy
class HelloWorld(object):
    @cherrypy.expose
    def index(self):
        return "Hello World!"
cherrypy.quickstart(HelloWorld())

运行示范：

5.2 方法二，代码：

import cherrypy  
class HelloWorld:  
    def index(self):  
        return "Hello world!"  
    index.exposed = True   #暴露设置为true，区别
cherrypy.quickstart(HelloWorld())

5.3 方法三，代码：

import cherrypy
class HelloWorld(object):
    @cherrypy.expose
    def index(self):
        return "Hello world!"
if __name__ == '__main__':
    cherrypy.quickstart(HelloWorld())

6 显示html的plotly的柱状图法

import cherrypy
class HtmlShow(object):
    @cherrypy.expose
    def index(self):
        return """
t
tt
ttJavascript与Plotly结合的可视化作图
t
t
tt

t
t
t
t
    
"""

if __name__ == '__main__':
    cherrypy.quickstart(HtmlShow())
