Pep8 says --max-line-length=79 but Django says --max-line-length=119. Both are associated with Python. Even in GitHub code review it is 119. I just want something that supports python with 119 characters and formats my document automatically rather than me doing it, as it formats with autopep8 with max line length = 79 — Mohit Kumar 23 secs ago

Well executor is single threaded so it make sense that heavy work might use more CPU that is available to single thread. The first tool to use here is a code review. After that I'd try a thread analysis tool stackoverflow.com/questions/51218228/… and also just looking at the OS load (top or Task Manager). — markspace 43 secs ago

@Eyeslandic Since this is a how to question, it's not really clear that it would be well received on code review. Just because the code works doesn't mean it is off-topic for stack overflow. I would also ask to that if you're going to redirect someone to code review please redirect them to our help center so that their question is more appropriate. When I redirect someone to stack overflow I always provide a link to the help center so that they know what is on topic. — pacmaninbw 15 secs ago

@Peter-ReinstateMonica I don't understand your point. Is your point that people shouldn't answer question on SO? Is your point that the presented solution is wrong? Is your point that c is "not usable for serious software development"? Funny how a lot of critical systems run successfully on c. It's like... there are competent programmers in this world... and ... best practices ... and ... code review and ... unit testing, integration testing, system testing and acceptance testing are a thing. — bolov 15 secs ago

@Mast okay I removed the second sentence. Should I remove the first one too? If so, maybe we should notify L.F. About this answer

@SᴀᴍOnᴇᴌᴀ (took me a while to understand what Mast meant, so didn't say anything earlier) IMO I think what you had was fluff, but I'd be happy for you to have left it. What you have now I think is fluff and should just be removed.
