I have literally never used a doubly-linked list in my life, and I'm pretty sure that most programmers can say the same thing.

As for the example... yeah, Python is pretty terrible (for writing production codebases, I think its a great language for short-lived, one-person projects). Interesting that you mention Python because if you're considering Python and Rust for the same use case that's pretty bonkers, for anything that you might possibly have used Python to do there are many more natural choices than Rust. If you wouldn't have done it in C/C++ ten years ago, you probably shouldn't be doing it in Rust today.
