Guide to: Learning Python Decorators

Guide to: Learning Python Decorators
Do you want to take your Python to the next level?
Python is easy to learn. You can learn the basics in a day and be
productive with it. But there are more advanced constructs that you
will eventually run across if you spend enough time with it. Don't be confused by these. Learn them, embrace them, and improve your code and others.
Â
Decorators
Decorators are pretty common in modern Python. While not strictly necessary,Â they can reduce code size while enabling control of function input,Â invocation and output. They also enable separation of responsibility and DRY. Many explanations of decorators are brief andÂ leave the reader somewhat confused. This book is an attempt to remedyÂ that. It is based off of popular tutorials given at PyCon and PythonÂ user groups. Without fail, attendees mention that "decorators nowÂ make sense". Not only do they understand decorators, but they can write themÂ as well.
Â
The guide covers:
Functions
Closures
*args
**kwargs
Decorating with functions
Decorating with classes
Alternate decorating methods
Write Python code like the masters
These constructs, while not necessary per se, allow you to be more succinct,
re-use code, and think about code in a different way. You will learn:
How the constructs work
When to use them
Real life examples from the standard library
Understand other's code
This book covers many of these intermediate constructs that are available in Python. The book covers both Python 2 and 3. Topics include:
In's and out's of functions
Closures
Decorators
Real world examples of their use
Based on popular tutorials and sessionsÂ
I have taught material similar to these constructs at popular tutorials at conferences such as PyCon, OSCON and Strata (and other
conferences). This book is based on my experience teaching and using
Python for many years. I hope you learn something while in the course
of your reading. Maybe it will help you in your next task, code
review, or job interview.

Up Your Advanced Python Skills
It is assumed that the reader has some knowledge of Python. You will walk away knowing the the in's and out's of closures and decorators, when to use them, and how to use them.
