Guide To: Learning Python Decorators: Python Guides (Unabridged‪)‬

Decorators are pretty common in modern Python. While not strictly necessary, they can reduce code size while enabling control of function input, invocation, and output. They also enable separation of responsibility and DRY. Many explanations of decorators are brief and leave the listener somewhat confused. This book is an attempt to remedy that. It is based on popular tutorials given at PyCon and in Python user groups.
