python web py入门（1）-web.py简介和安装

1.web.py 简介 web.py是一个轻量级的python web框架，简单而且功能强大。相对flask和Django，web.py更适合初学者来学习和了解web开发的基础知识。

2.web.py的安装不用说，前提条件是安装了python环境。官方网站：http://webpy.org/, 可以看看文档，介绍如何安装，和入门教程等资料。

Windows下安装环境 python 3.6 从网站：https://github.com/9073204qq/webpy 下载源码

pip install db pip install utils

到下载源码的目录： python setup.py install 运行这个命令行，会输出如下：

4.测试安装是否正常

创建测试代码：

import web

urls = ( '/(.*)', 'hello' )

app = web.application(urls, globals())

class hello: def GET(self, name): if not name: name = 'World' return 'Hello, ' + name + '!'

if name == "main": app.run()

结果输出如下：
