Threads can be put onto separate cores too, and can have their affinities set. But because of the GIL, actual CPython code can't run on two cores at once. You might be able to have two Python threads running at once if they're calling into C modules most of the time, but it's much safer to either go multiprocessing or to use I/O bound threads (eg socket handlers).
