- E301 expected 1 blank line
- E302 expected 2 blank lines
- E303 too many blank lines
- E305 expected 2 blank lines after class or function definition
- E306 expected 1 blank line before a nested definition
Fixed automatically with autopep8:
git ls-files | grep py$ | xargs autopep8 --in-place \
--select E301,E302,E303,E305,E306
Manually fix issues in project.py caused by misuse of block comments.
