Python 101, Python code, Python decorator, Python descriptors

Last time I explored a number of useful Python decorators. The post was a revisit to a topic I first posted about five years ago [see Python Decorators, part 1 and Python Decorators, part 2]. Back then I didn’t really know what to do with decorators, but I could see they were useful.

Since then, I’ve found many applications for them, hence the revisit to the topic. In this post, we’ll continue looking at useful applications. If nothing else, they may provide some ideas for decorators of your own.

But that changed during the last five years as I’ve had occasions to actually use decorators in code. They are extremely handy in certain situations. Today’s post takes a more useful look at Python decorators.

This time I pick up where I left off by exploring decorators modifying return values, decorators that take parameters, and decorators in classes.

Aspect-Oriented Programming, Python 101, Python code, Python decorator

I’ve been playing around with what Python calls decorators. They’re a built-in way of implementing Aspect-Oriented Programming techniques in Python. In fact, they’re quite powerful.

Since they aren’t a common language feature, they can be a little confusing at first, so I thought I’d try my hand at laying out how they work.
