I don't think that's quite right. It's more like if you have to choose a language before you know what you're doing, Python is the best choice. For anything large enough it's multiple places down the list, but you really don't want to have to learn Rust and possibly reinvent wheels for your quick boilerplate hack.

I literally used to say this last decade, but as I grew experienced with more languages/paradigms/systems, it became 3rd best, then 4th, until I realized it actually not really great at anything other than there is an large ecosystem around it (wildly varying in quality). To some that might be enough, & going outside what you know isn’t typically the most wise thing to do, but it’s not particularly simple, or readble, or performance, or composable, or offering great patterns. Anything that used Python in Nixpkgs tend to be the most unreliable software for actually building & using.
