"like this" is complicated, because different foundations do different things, but, beyond the Python Software Foundation, there is:

* The OpenJS Foundation (Node)

* Ruby Central is similar but also different

* Parrot (for Perl 6...) had a foundation, not clear on what the project is like now though

* https://www.perlfoundation.org/

And of course, many many foundations that support open source projects that aren't programming languages.

Zig also debuted their foundation a few weeks ago; https://ziglang.org/zsf/
