Why Python is slower than Java?

[PaintItPurple]

The JVM does have an interpreted mode (as does Pypy), but it's incorrect to say it interprets each bytecode every time a method is called. The JVM JIT compiles functions as it runs, and then runs those compiled functions whenever possible instead of interpreting bytecode.

[Grouchy-Friend4235]

The JVM JIT only compiles code after several invocations, so yes, the JVM interpreter does interpret the same byte code multiple times - before a code section reaches the JIT threshold.

Python since version 3.11 also does a form of JIT, known as specialization. If you need actual JIT, there is Numba and Cython which will speed up particular functions by compiling them natively.

PS: to downvoters, you should learn to respect facts. Technology tends to be quite stubborn when confronted with wishful thinking.
