The former is a property of Python, which is a programming language. I
agree with your assessment :-)

The latter is not a property of Python; a programming language doesn't
have runtime performance. Rather, runtime performance is a property of
some specific *implementation* — that is, the runtime Python machine.

There are numerous Python runtimes, and they have different performance
characteristics on different hardware and operating systems.


You might be talking about performance on CPython. But you might not! I
don't know.

Have you looked at PyPy – Python implemented in Python – and compared
its performance?
