>I shy away from Python for anything where performance might one day be an issue if there are only a few bottlenecks that have a significant impact on the performance you could rewrite only those parts to C/Rust. This might be a good aproach especially in a situation where performance is not an issue right now but might be in future. When it actually becomes an issue only the part that actually affects the performance could then be rewritten to C. Of course this approach doesn't always make much sense, but quite often there is a small part of the code that impacts the performance the most and only that part would need to be rewritten, while the rest of the code could still enjoy a language more productive to write in. Similarly a microservice(ish) architecture comes handy with this
