How did you run the Python version? From the comments it looks like
running it using PyPy improves the speed about 10x (JIT compiled I
think). People have also created Python versions using numeric
libraries which are much faster than the original. I'm not sure what
optimizations have been included.

The original video was C++ vs C# vs Python:

Python was slower as expected.
Well, I'm seeing different results on z/OS. There is no PyPy on z/OS.
