Design patterns and Python

This book focuses on design patterns in Python. Python is different than most common programming languages used in popular design patterns books (usually Java [FFBS04] or C++ [GOF95]). It supports duck-typing, functions are first-class citizens, and some patterns (for instance, iterator and decorator) are built-in features. The intent of this book is to demonstrate the most fundamental design patterns, not all patterns that have been documented so far [j.mp/wikidpc]. The code examples focus on using idiomatic Python when applicable [j.mp/idiompyt]. If you are not familiar with the Zen of Python, it is a good idea to open the Python REPL right now and execute import this. The Zen of Python is both amusing and meaningful.
