How do I disable a Pylint warning?

461

I'm trying to disable warning C0321 ("more than one statement on a single line" -- I often put if statements with short single-line results on the same line), in Pylint 0.21.1 (if it matters: astng 0.20.1, common 0.50.3, and Python 2.6.6 (r266:84292, Sep 15 2010, 16:22:56)).

I've tried adding disable=C0321 in the Pylint configuration file, but Pylint insists on reporting it anyway. Variations on that line (like disable=0321 or disable=C321) are flagged as errors, so Pylint does recognize the option properly. It's just ignoring it.

Is this a Pylint bug, or am I doing something wrong? Is there a way around this?

I'd really like to get rid of some of this noise.

python pylint

I had this problem using Eclipse and solved it as follows:

In the pylint folder (e.g. C:\Python26\Lib\site-packages\pylint), hold Shift, right-click and choose to open the windows command in that folder. Type:

lint.py --generate-rcfile > standard.rc

This creates the standard.rc configuration file. Open it in Notepad and under [MESSAGES CONTROL], uncomment disable= and add the message ID's you want to disable, e.g.:

disable=W0511, C0321

Save the file, and in Eclipse → Window → Preferences → PyDev → *pylint, in the arguments box, type:

--rcfile=C:\Python26\Lib\site-packages\pylint\standard.rc

Now it should work...

You can also add a comment at the top of your code that will be interpreted by Pylint:

# pylint: disable=C0321

Pylint message codes.

Adding e.g. --disable-ids=C0321 in the arguments box does not work.

All available Pylint messages are stored in the dictionary _messages, an attribute of an instance of the pylint.utils.MessagesHandlerMixIn class. When running Pylint with the argument --disable-ids=... (at least without a configuration file), this dictionary is initially empty, raising a KeyError exception within Pylint (pylint.utils.MessagesHandlerMixIn.check_message_id().

In Eclipse, you can see this error-message in the Pylint Console (windows* → show view → Console, select Pylint console from the console options besides the console icon.)
