Review comment:
> How did you choose which to rules to permanently exclude and which to fix
in this PR?
That's a good question.
Obvious errors to exclude:
- `useless-object-inheritance`: obviously we need to keep this until we drop
python2 support
- `import-outside-toplevel`: scoped imports are pretty fundamental. I
don't even understand why they added this as an error
Probably worth solving now:
- `expression-not-assigned`: used in a few places in one test. Could be
worth making explicit exclusions for the test cases so that the problem is not
spread elsewhere
- `singleton-comparison`: e.g. `x == None`. this only occurs in a few
places, so would be easy to squash now
Could be added to a ticket for later:
- `no-else-raise/break/continue`: this pattern is pretty prevalent
throughout the code. could be worth fixing, but pretty time consuming. good
newbie task.
Here's the full output (excluding the first two). Let me know if there are
other errors you'd like to fix in this PR or add to a follow-up ticket.

Worklog Id: (was: 328332)
Time Spent: 6.5h (was: 6h 20m)
> Upgrade to pylint 2.4
> ---------------------
>
> Key: BEAM-8350
> URL: https://issues.apache.org/jira/browse/BEAM-8350
> Project: Beam
> Issue Type: Improvement
> Components: sdk-py-core
> Reporter: Chad Dombrova
> Assignee: Chad Dombrova
> Priority: Major
> Time Spent: 6.5h
> Remaining Estimate: 0h
>
> pylint 2.4 provides a number of new features and fixes, but the most
> important/pressing one for me is that 2.4 adds support for understanding
> python type annotations, which fixes a bunch of spurious unused import errors
> in the PR I'm working on for BEAM-7746.
> As of 2.0, pylint dropped support for running tests in python2, so to make
> the upgrade we have to move our lint jobs to python3. Doing so will put
> pylint into "python3-mode" and there is not an option to run in
> python2-compatible mode. That said, the beam code is intended to be python3
> compatible, so in practice, performing a python3 lint on the Beam code-base
> is perfectly safe. The primary risk of doing this is that someone introduces
> a python-3 only change that breaks python2, but these would largely be syntax
> errors that would be immediately caught by the unit and integration tests.
