I mean, you’ve basically described why people use Python, it’s a way to use C/C++ without having to write it.

And ill take that reason every single day. I could spend days or more working out particular issues in C++, or I could use a much nicer to use glue language with a great ecosystem and a huge community driving it and get the same task done in minutes to hours.

I tried to statically link DuckDB to one of my C++ project earlier this year and it took me 3 days to have something working on Windows/Linux/MacOS (just to be able to use the dependency)

While I'm not a C++ expert, doing the same in Python is just one pip install away, so yeah both "richness" and "ease of use" of the ecosystem matters

You made my point for me: DuckDB is already in C++ (so C++ is rich enough), but hard to glue with other pieces, and you don't want to put in that effort, so you use Python.
