false negative "too-many-arguments" about pylint HOT 5 CLOSED

Hey @buhtz it looks like expected behaviour because one of the parameter names begins with the string ignored_.
That parameter is excluded from the count of total parameters.

from pylint.

Technically I do understand. But what is the reason behind it? How does this improve code quality?

from pylint.

The reason is that the default value for the --ignored-argument-names setting includes ignored, which you are using in your snippet. That's unlucky in your case, but it has a fix -- you can set --ignored-argument-names to something else if you have a legitimate use case for an argument name that begins with that word.

I am still not convinced but I would minimally treat this as a bug in documentation. The docu page about that error/rule should mention the exceptional cases caused by ignoored-argument-names.

This would be greatly alleviated by #9184
