codebase does not pass linting, and it should, so that passing linting can be part of the test suite #130

Open sneak opened 6 years ago

sneak commented 6 years ago

The codebase conforms to pep8 formatting now (after I fixed it) but it still doesn't pass flake8 linting checks.

see current list of failures here:

https://circleci.com/gh/steemit/steem-python/30

We should fix this and merge in the add-linting-support-to-tests branch to ensure that no sloppy or error-prone code makes it onto master. This should aid in code review, much like -Werror does in steemd.

branch: https://github.com/steemit/steem-python/tree/add-linting-support-to-tests
