Personally, I find many of the design patterns apply but require modification.
For example, the Factory pattern is mostly to work around the fact that it's difficult in Java and C++ to dynamically load classes. Not so in Python, especially with exec. A simple configuration file and an exec call can replace an entire Factory pattern, with the same result. The ideas are fine, but sometimes it's best to keep things simple. I find that DP junkies don't tend to keep things simple. -- http://mail.python.org/mailman/listinfo/python-list
