[编辑] Install

wget http://webpy.org/web.py-0.2.tar.gz
python setup.py install // install to /usr/local/lib/python2.4/site-packages/web
touch code.py
import web
urls = (
  '/hello/webpy', 'index'
)
class index:
 def GET(self):
   print "hello, webpy"

if __name__ == "__main__": web.run(urls, globals())

python code.py
http://localhost:8080/hello/webpy :)

Build on Python 2.3

File "utils.py", line 528
   return .join(c for c in str(string).split('.')[0] if c.isdigit())
change to return .join([c for c in str(string).split('.')[0] if c.isdigit()]) 
python setup.py install // ok :)

[编辑] Template

mkdir templates
cd templates
touch index.html

[编辑] Database

For MySQL databases, use MySQLdb and for Postgres use psycopg2.

web.config.db_parameters = dict(dbn='postgres', user='username', pw='password', db='dbname')
web.config.db_parameters = dict(dbn='mysql', user='username', pw='password', db='dbname')

[编辑] Example

[编辑] 常见用法

import web
urls = (
  '/', 'index'    )
class index:
   def GET(self):
       print "Hello, world!"

web.internalerror = web.debugerror
web.header("Content-Type","text/html; charset=utf-8")

web.redirect(web.ctx.home+'/page/'+name)
if __name__ == "__main__": web.run(urls, globals())
if __name__ == "__main__": web.run(urls, globals(), web.reloader) // more helpful error messages

$def with (name)
$if name:
    I just wanted to say hello to $name.
$else:
    Hello, world!

render = web.template.render('templates/')
cache=False
name = 'Huihoo'    
print render.index(name)

i = web.input()
n = web.insert('todo', title=i.title)
web.seeother('/')

So what Python framework did you use?

web.py, the web application framework of choice for discriminating hackers. web.py is itself built upon Cheetah. The data is stored in a PostgreSQL database and served by Lighttpd.

Yandex, a Russian traffic provider whose homepage alone receives 70 million daily page views, uses web.py for certain projects.
