Decorated Concurrency - Python multiprocessing made really really easy tl;dr There's a new interesting wrapper on Python multiprocessing called deco, written by Alex Sherman and Peter Den Hartog, both at University of Wisconsin - Madison. It makes Python multiprocessing really really easy. The paper is here (PDF) and the code is here: https://github.com/alex-sherman/deco. This library is based on
A guide to Python's function decorators
Python is rich with powerful features and expressive syntax. One of my favorites is decorators. In the context of design patterns, decorators dynamically alter the functionality of a function, method or class without having to directly use subclasses. This is ideal when you need to extend the functionality of functions that you don't want to modify. We can implement the decorator pattern anywhere,
Improve Your Python: Decorators Explained
Looking for Python Tutoring? Remote and local (NYC) slots still available! Email me at jeff@jeffknupp.com for more info. I've previously written about "yield" and generators. In that article, I mention it's a topic that novices find confusing. The purpose and creation of decorators is another such topic (using them, however, is rather easy). In this post, you'll learn what decorators are, how they
The Dark Side of Decorators - Freedom Dumlao
Recently a bug report was filed on the Flask-Classy issue tracker at Github which caught me by surprise. This was a bug so glaring that the fact I hadn’t seen it myself was a shock, but even more shocking was that nobody else had reported it either. The bug was simple to describe: If you used any decorator (but didn’t use the @route decorator), Flask-Classy would not auto generate the correct rout
DRY Principles through Python Decorators
Python decorators are a powerful tool to remove redundancy. Along with modularizing functionality into appropriate bite-sized methods, it makes even the most complex workflows into concise functionality. For example, let’s look at the Django web framework, which handles requests by methods which receive a method object and return a response object: A case I ran into recently was having to write se
Decorators, Scrapers and Generators | CUPPSTER.COM
Whoever said scraping web pages can’t be fun never tried it using Python decorators and generators! We’ll use this mini-framework to fetch all the upcoming comic book releases from one of my favorite online comic book stores. A couple of interesting things going on here programmatically: 1) using decorators that are static methods of a class that maintains some state for the decorated operations a
DailyJS: Decorating Your JavaScript
The decorator pattern, also known as a wrapper, is a mechanism by which to extend the run-time behavior of an object, a process known as decorating. The pattern is often overlooked because its simplicity belies its object-oriented benefits when writing scalable code. Decorating objects is also neglected in JavaScript because the dynamic nature of the language allows developers to abuse the malleab

Blog :: Understanding Python Decorators in 12 Easy Steps! 1 July 2012 Ok, perhaps I jest. As a Python instructor, understanding decorators is a topic I find students consistently struggle with upon first exposure. That’s because decorators are hard to understand! Getting decorators requires understanding several functional programming concepts as well as feeling comfortable with some unique featur
