Getting started with metaprogramming in Python

. However, in Python 2.2, the methods involved in the metadata can be better exposed. Python V2.2 explicitly does not use only one special (usually hidden) Metadatabase to create each class object. Now, programmers can create subclass of the original Metadatabase type, or even dynamically generate classes using various Metadatabase classes. Of course, it is only because you can operate the MetaBase in Python 2.2, which does not indicate the reason you may want to do so. Furthermore, you do not n

His approach always starts with some simple calculations to find the best balance between quality and speed for a particular process. In many areas, from machine translation to search quality, you always try to weigh the amount of computing you can do with each query, he says. You may not be able to
