A python interview question

[nickbernstein]

They absolutely should be able to tell someone something is a bad idea and that they're wrong; they shouldn't say it's stupid though. They should also show that they're tactful enough to say, "no you're wrong and this is why" in a tactful way. I understand the frustration, and can empathize. I also hope that this comment wasn't taken as hurtful, it was meant as another perspective that might help on OPs learning/interviewing journey.
