Clean Code in Python

Transforming parameters

We have mentioned before that decorators can be used to validate parameters (and even enforce some preconditions or postconditions under the idea of DbC), so from this you probably have got the idea that it is somehow common to use decorators when dealing with or manipulating parameters.

In particular, there are some cases on which we find ourselves repeatedly creating similar objects, or applying similar transformations that we would wish to abstract away. Most of the time, we can achieve this by simply using a decorator.
