Thanks again to all persons that commented so far.
what's your opinion about a code-formatter bot for cpython. Pros, Cons, where could be applicable (new commits, new workflow, it doesn't make sense), ...
- At least it should follow PEP 7 ;-) - ...
There seems to be too much implicit information on the lines above. Sorry for that. I'll try to clarify.
From my point of view (not a core-dev) the reviews seem to be one of the bottlenecks to the commit throughput, and I noticed on the other PEP 7 thread that time is taken to review such, IMHO, (and as Andrew also noted) trivialities. Thus the basic idea was to get that noise away from the reviews, somehow (better upfront, but why not after, accidental PEP 7 noise commits can happen). Well, people should first agree on that PEP and then some automatic could come.
Please notice that the interaction is not just: core-dev committing to a repo or a bot committing to a repo but external-contributor that tries to minimize review iterations. I have no problem with some process (call it now a bot or script) that just changes a patch/file to reduce that cycle (but it could, run on all the workflow points you mentioned, plus on the PR-site as a kind of an advisor/mentor).
