WARNING: This file is programatically generated.
This file is parsed by pylint-ignore
to determine which
Pylint messages
should be ignored.
- Do not edit this file manually.
- To update, use
pylint-ignore --update-ignorefile
The recommended approach to using pylint-ignore is:
- If a message refers to a valid issue, update your code rather than ignoring the message.
- If a message should always be ignored (globally), then to do so
via the usual
pylintrcorsetup.cfgfiles rather than thispylint-ignore.mdfile. - If a message is a false positive, add a comment of this form to your code:
# pylint:disable=<symbol> ; explain why this is a false positive
