Note that it sounds like a snide remark but it doesn't have to be. One could interpret it as, "Do you want to simply get things done, and not bicker endlessly about microoptimizations or where the braces go? Python is for people who simply want to complete their tasks and then go home and spend their time doing more stuff they think is fun."

It's not necessarily a bad thing to be productive, instead of inventing new problems for yourself to keep having programming things to do.

(Note that none of this necessarily reflects my personal opinion; it is just an alternative way to read the grandparent.)
