No python has way more packages like the op said. You can't start projects in rust where you need a significant amount of dependencies because rust is not there yet.
Language wise rust is better the python in every way except for compile times.
I imagine that in addition to having more packages, it is easier to hire developers who know Python than who know Rust. Current tiobe index puts Python at #3 (rating=10.86%) and Rust at #30 (rating=0.49%). If you already have a team experienced in Rust, then it may be a good choice, but if you are expecting to grow your team, you may want to pick a language based on popularity.
Language-wise, it feels like they are intended to solve different problems, so Python vs Rust is a weird comparison. Granted, that may because I started learning Rust as a replacement for C++, so that has been my point of comparison.
Generally I wouldn't advise hiring based on the language the candidate knows anyway. Almost all mainstream languages are so similar in concepts that it doesn't really matter anyway.
