The global interpreter lock is very, for cluding you can't do multiple computation computations at the same time. Because CPython only allows to be used at one core at a time. Basically computational parallelism is not such a thing. And Python, if you're you got to drop down to C or multiple fork the processes or something like that, right? Exactly. But when you when you're doing IO, which doesn't involve any Python, you can use threading to do things like, you know, file system,. That's great for Python's threading. But otherwise you don't really want to be using it.
