So how should things work? The first principle is that code should be clear and simple. If you want to output some text, you call web.output. If you want to get form input, you call web.input. There’s nothing particularly hard to remember.
The second principle is that web.py should fit your code, not the other way around. Every function in web.py is completely independent, you can use whichever ones you want. You can put your files wherever you like, and web.py will happily follow along. If you want a piece of code to be run as a web app, you call web.run, you don’t put your code in the magical place so that web.py can run you.
The third principle is that web.py should, by default, do the right thing by the Web. This means distinguishing between GET and POST properly. It means simple, canonical URLs which synonyms redirect to. It means readable HTML with the proper HTTP headers.
