PEP 8 and Python decorators

Question

I'm working on a project where I have a class with some 10ish decorators on it, where I'm using them to provide validation on some methods and attributes (if it's relevant, the validation is very general, and re-used elsewhere on other classes). I've been advised by a friend who is a lot more of a PEP8 stickler than I am that this is bad form---however, I cannot find a cite for that, or even good advice on what constitutes a good use of a decorator versus a bad or non-essential one.

My own introduction to using decorators came from Flask, where they provide routing information, and can be stacked a couple deep. Could someone provide cited information on proper versus improper decorator usage, and better alternatives?

Answer 1

What matters in Python is code readability. 10 or so decorators might be pretty hard to keep track of, while 2 o 3 are easier to read. You don't need a convention for every character you type: sometimes, you just have to go for what is easier to read
