What's New in Pylint 2.4

Release:2.4
Date:TBA

Summary -- Release highlights

New checkers

  • A new check class-variable-slots-conflict was added.

    This check is emitted when pylint finds a class variable that conflicts with a slot name, which would raise a ValueError at runtime.

    For example, the following would raise an error:

    class A:
        __slots__ = ('first', 'second')
        first = 1
    

Other Changes

  • A file is now read from stdin if the --from-stdin flag is used on the command line. In addition to the --from-stdin flag a (single) file name needs to be specified on the command line, which is needed for the report.
