使用python写一个web

先编写hello.py，实现Web应用程序的WSGI处理函数：

# hello.py

def application(environ, start_response):
    start_response(‘200 OK‘, [(‘Content-Type‘, ‘text/html‘)])
    return ‘<h1>Hello, %s!</h1>‘ % (environ[‘PATH_INFO‘][1:] or ‘web‘)

再编写一个server.py，负责启动WSGI服务器，加载application()函数：

from wsgiref.simple_server import make_server

from hello import application

httpd = make_server(‘‘, 8000, application)
print "Serving HTTP on port 8000..."

httpd.serve_forever()
