Not with a good JIT compiler like PyPy.

You might be interested in pypy or nuitka

I'm curious about the performance improvements, I guess one day it will match pypy or numba?

Does this mean python performance is finally competitive with those fancy JIT languages now?

Pypy JIT is way faster than CPython

Have you tried pypy? Might be interesting comparison.

I think you should check out PyPy. It has a JIT which significantly improves performance for many use cases.

Why do competitive Python programmers use PyPy instead of CPython?

dilawar Apr 24, 2018 View on HN

I wonder why the author did not compare performance of pypy? I guess pypy is jit compiler.

There is a JIT for python: http://pypy.org/
