Because it's not a statically typed language for the most part, which brings in an entire class of bugs of its own. It's also an extremely mutable language.

Great for scripts, but there is a reason why most large companies start bolting on types on whatever dynamic language they started with.

Most production languages that nominally do some static typing aren't statically very safe - certainly Java, Go, C/C++ are rife with runtime errors. After the required testing to eliminate those, it's not clear Python is significantly different.

Edit: also, Python does eagerly signal type errors, unlike say Javascript or C, so you don't get silently wrong answers. C is the default language in auto industry. .

Yeah, this is a bit of whataboutism, certainly it would be nice if the state of the art in production languages was closer to the ideal of statically verified... Haskell and Rust are in the right direction, and would be clearly superior in this regard

I wasn't implying that static types solve everything, they just make things n+1 better and remove a class of bugs.

Statically typed languages are mature and you have no excuse not using them if your doing anything that approaching a need for reliability. Cars do, social cat pictures, not so much.

What about Erlang?
