Unicode support in Python: Frustrations and Solutions
To be honest, I think the support of unicode in Python before Python 3, being totally honest, is a f*knig nightmare. I prefer PHP 5.x support for unicode (= zero support).

Serializing native data in Python

How to get user-agent in Google App Engine using Python
User-Agent tells which is the client application that is making the request. It tells if it’s a browser (and information which browser it is), if it’s a robot (for example a Google/Yahoo/Bing spider), … In theory the string is present in all HTTP headers, no matter which client is doing the request, but it might [...]
Max URL (or GET) length in Google App Engine
I’ve done some tests in order to evaluate what is the maximum length of a URL that the different browsers can handle, and I ended up with a restriction on the server-side.
