Bug description

Similar to #5478

/tmp/test.py:

import logging
from enum import Enum


class ConstraintType(Enum):  # pylint: disable=missing-class-docstring,too-few-public-methods
    DISTANCE = 0
    FORCE = 1


constraintType = "none"

switch = {
    "distance": ConstraintType.DISTANCE,
    "force": ConstraintType.FORCE
}

if constraintType not in switch.keys():
    logging.error(f"Forgot to add a constraint type \"{constraintType}\" to the AST")
    result = None

result = switch[constraintType]

Expected behavior

The error should not appear, that is an if, not a loop.

I think this is expected behaviour and is documented as such: https://pylint.pycqa.org/en/stable/user_guide/messages/convention/consider-iterating-dictionary.html

Emitted when the keys of a dictionary are iterated through the .keys() method or when .keys() is used for a membership check..

Perhaps the content of the message could be updated to not necessarily mention iteration; what do you think @EmmanuelMess ? Edit: Perhaps something like: "Use of .keys() is not required here"?

That would make it more clear, yes. As it is worded now makes little sense in this context.

Thanks! The name ‘consider-iterating-dict’ could also be updated so I’ll remove the ‘needs pr’ label until there is interest in that also from others.
