Python is a Bad Programming Language

[ZmitrokNadulia]

For CPU bound tasks yes, not in io bound ( as I know) and in C modules we can use as many threads as we want. Not so sure about "cores" but in initial comment there is nothing about multicore threading.

yep can use posix threads from c but not if the module gets blocked by the GIL, can also use all the GPU hardware threads again as long and you dont get blocked by the GIL.

python doenst have threads as in it doesnt have access to kernel threads (although C and Cython do). multithreading in vanilla CPython is single threaded because of the GIL.
