Currently we only enforce PEP8 standards on lines of code that have changed in a PR. We need all code to be PEP8 compliant so we don't have a mixed message on our standards.
minimally synapseclient and synapseutils should be free from PEP8 issues
unit/integration tests free from PEP8 would be nice also if but not critical
we should configure pep8speaks to use flake8 as its linter that way you can get the same lint result from the command line and in builds that you'd see after submitting a PR
