Ho yes ??? Why so, please ? Care to point to anything *wrong* in the 
above statement ?

Which is known as JIT compilation - and there are a couple attempts at 
it in Python too.

Anyway, the JIT compiler is not part of the Java spec (while the 
byte-code/VM is), and its not garanteed to be there on each an every 
Java VM.

And ?

I fail to see how the existence of JIT compilers in some Java VM changes 
anything to the fact that both Java (by language specification) and 
CPython use the byte-code/VM scheme.
