As much as I'm loathe to enter into "language wars" style commentary, I think I agree with @clauswilke.com here. The lack of NSE and native missing values is really bad for Python as a data science language (as, in fairness, is the unhinged OOP situation in R)
Python is not a great language for data science. Part 2: Language features
It may be a good language for data science, but it’s not a great one.

More people need to read "Why does he do that?" because a great deal of people are bullied and we don't turn into abusers. The narrative these people are victims is perverse to the goal of stopping abuse because it's not only false but contributes the cycle.
