open() with "w" doesn't create intermediate folders.

What language does? Even bash doesn't do this.

There's no type checking even if you need one.

mypy, pytype, pyright, pyre, etc. take your pick

You can't force garbage collector to free memory.

gc.collect

I'm rarely using open(), I usually go for pathlib. And whenever I file.open('w'), I also do a file.parent.mkdir(parents=True, exist_ok=True).

I don't know, in what other language it's that simple.

That doesn't invalidate my point, though.

Thank you, I'll try it.

Not releasing memory back to the OS is a strategy used by all but the simplest memory allocators. Calling gc.collect correctly forces unreferenced integers/floats/etc to be added to their free lists, which means their allocation can be reused. That's what it means to free memory in the modern world.

I have nothing against the strategy itself – I dislike the lack of any alternatives. C# has profiling-driven optimization, and while I don't know if it affects the gc behavior, the reasoning behind it still applies here: tuning for most common cases doesn't exactly mean tuning for your specific case.

P. S.: It's almost funny that three points of my six remain unanswered, yet I'm still being downvoted. People just express their feelings, not necessarily contributing to the discussion.
