One possibility is a file.py that is called by your framework. The interface could be something like

  def doth_match(*args):
    return True  # the predicate

  def doeth_thou(*args):
    # processing things
    return {}  # status object for example

The framework loops and checks the first function; if true, then execute the second function. And then break or continue for other rule files (or objects).

There could be multiple files rule1.py, rule2.py, etc that check and do different things.

I think the parent's argument is that wherever in your framework you're calling `doth_match` and then `doeth_thou`, you have a single function that's both deciding and acting. There has to be a function in your program that's responsible for doing both.

A function that asks a question with one function call and calls another based on the answer isn’t doing any work or asking any questions. It’s just glue code. And as long as it stays just glue code, that’s barely any of your code.
Asking for absolutes is something journeymen developers need to grow out of.
The principle of the excluded middle applies to Boolean logic and bits of set theory and belongs basically nowhere else in software development. But it’s a one trick pony that many like to ride into the ground.
