Oh definitely, but at least Python's stdlib is relatively consistent, which helps packages be a little more so.

My favourite example is t.test, which is not a t method for the test class, unlike summary.lm which is.

And there's like 4 different styles of function naming in base & stats alone.

Python has problems (for gods sake, why isn't len a method?) but it's a little more consistent.

I used to think that R was responsible for a lot more of the mess than I now do, having seen the same kind of DS code (and I am a DS) written in both Python and R.

And it would be sweet if R had a pytest equivalent, if I never have to write self.assertEqual again, it'll be too soon.
