Is it possible to ignore one single specific line with Pylint?

Question

I have the following line in my header:

import config.logging_settings

This actually changes my Python logging settings, but Pylint thinks it is an unused import. I do not want to remove unused-import warnings in general, so is it possible to just ignore this one specific line?

I wouldn’t mind having a .pylintrc for this project, so answers changing a configuration file will be accepted.

Otherwise, something like this will also be appreciated:

import config.logging_settings # pylint: disable-this-line-in-some-way

Answer 1

I believe you’re looking for…

import config.logging_settings  # @UnusedImport

Note the double space before the comment to avoid hitting other formatting warnings.

Also, depending on your IDE (if you’re using one), there’s probably an option to add the correct ignore rule (e.g., in Eclipse, pressing Ctrl + 1, while the cursor is over the warning, will auto-suggest @UnusedImport).

Answer 2

import config.logging_settings # pylint: disable=W0611

That was simple and is specific for that line.

You can and should use the more readable form:

import config.logging_settings # pylint: disable=unused-import

Pylint message control is documented in the Pylint manual:

Is it possible to locally disable a particular message?

Yes, this feature has been added in Pylint 0.11. This may be done by adding
# pylint: disable=some-message,another-one
at the desired block level or at the end of the desired line of code.

You can use the message code or the symbolic names.

For example,

def test():
    # Disable all the no-member violations in this function
    # pylint: disable=no-member
    ...
    # pylint: enable=no-member

apply to a specific line only:

global VAR  # pylint: disable=global-statement

or for less verbosity, disable the ONLY following line (pylint 2.10+):

# pylint: disable-next=global-statement
global VAR

Pylint’s manual also has further examples.

There is a wiki that documents all Pylint messages and their codes.

Checkout the files in https://github.com/PyCQA/pylint/tree/master/pylint/checkers. I haven’t found a better way to obtain the error name from a message than either Ctrl + F-ing those files or using the GitHub search feature:

If the message is "No name … in module …", use the search:

No name %r in module %r repo:PyCQA/pylint/tree/master path:/pylint/checkers

Or, to get fewer results:

"No name %r in module %r" repo:PyCQA/pylint/tree/master path:/pylint/checkers

GitHub will show you:

"E0611": (
    "No name %r in module %r",
    "no-name-in-module",
    "Used when a name cannot be found in a module.",

You can then do:

from collections import Sequence # pylint: disable=no-name-in-module

In addition to the accepted answer:

You can re-enable the error checking adding pylint: enable:SPECIFIC_ERROR

For example, I have this in my code:

import time
import datetime
import os
import sys
# pylint: disable=import-error
import serial
# pylint: enable=import-error

This way you can ignore a single error on a single line without having to disable checking that error in the whole file
