For multiple warnings it is said in the docs "they are not rules unanimously accepted, and PEP 8 does not enforce them". But in the case of W503 and W504, it is more than that: pep8 says that new code should use the other convention:
"In Python code, it is permissible to break before or after a binary operator, as long as the convention is consistent locally. For new code Knuth's style is suggested."
I know that these warnings are not supposed to be activated by default, but they are on some editor plugins using pycodestyle (like the great Sublime Text plugin Anaconda).
I suggest that these two warnings be completely removed.
It's a bug that those tools enable both by default. The rules exist there so someone may use one or the other to enforce the chosen convention locally.
I find at least the W504 extreamly confusing as it doesn't even tell me how to rewrap the code to make it pass.... so I am not surprised people want to eradicate it.
A rule like should exist only if it able to tell you what to fix it. For the moment I am still trying to find some examples...

W503 doesn't tell you either. I'm not sure what this has to do with anything. Compare

PEP-0008 is the source of the examples you want.
