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
...
global VAR # pylint: disable=global-statement
The manual also has further examples.
There is a wiki that documents all Pylint messages and their codes.
