Again: if you insist on doing everything yourself - then of course any 
library or framework isn't for you.


But then do you deal with headers correctly? Do you respect character 
encodings? Form-encodings? Is your generated HTML valid? Are 
timestamp-formats generated according to RFCs for your cookies? Do you 
parse content negotiation headers?

I think you underestimate the task it is to make a webapplication good. 
And even if not, what you will do is ... code your own webframework. 
Because there is a lot of boilerplate otherwis. If that's a 
learning-experience your after, fine.

Besides, yes, you can get all these things nonetheless. You just don't 
need them most of the time.

And at least pylons/TG2 lets you return whatever you want instead, as a 
string. Not via "print" though - which is simply only for CGI, and no 
other means (e.g. mod_wsgi) of python-web-programming.
