Python and JavaScript have similarly good formatters (as long as your idiot colleagues don't insist on using yapf instead of Black, despite yapf producing non-deterministic output!). In fact I would say Rust is probably behind Prettier in terms of auto formatting. The rustfmt output is less pretty (subjective I know), the devs have made several strange decisions and it seems to be semi-abandoned (maybe partly because the devs were ... shall we say not as friendly and welcoming as the Rust community likes to bleat on about).
