I'm sorry but if your only reason why PHP and JS are less "clean" than Python is because they have brackets and parenthesis, you're sharing your inexperience, not your experience.
I meant "all those brackets and parentheses" as a synecdoche. I definitely don't mean my opinion to be a comment on any of the actual technical benefits of JS/PHP/Python. Just explaining the reason I've most recently preferred the act of writing one over the other.
