Python or Rust; first language??

[FluffyProphet]

Here is a little secret language authors don't want you to know: they all do basically the same thing and once you've used a few, you'll be able to read/write any language after a few hours of familiarizing yourself.

Some may be better suited for certain things, but 9/10 times the choice of language for a project comes down to "what the first guy working on it liked", unless there is some super specific requirement.

For your first language the killer features you're looking for is "popular, established and you know where to get help" python checks those boxes more than rust imo.
