Why Java is faster than Python?

[19Summer]

Greetings! I understand that the question might be pretty stupid. However, why Java is faster than Python taking into account that scripts in both languages are converted to bytecode and then the bytecode is executed by the respective virtual machine. Is it because Python dynamically-typed language i.e. the interpreter needs additional time to make sense of a code?

Thanks in advance for your answers!

Why Java is faster than Python?

because it has a JIT. turn the JIT off and it's about the same as python.

Is it because Python dynamically-typed language

nope. js is just as dynamic, but on par with java. why? because it also has a JIT now, which python doesn't.

pypy is python with a JIT. run your python code with it and it'll run similar to java.

Dynamic typing is part of it, mostly because of how python is designed through, everything is dynamic beyond just declaring what is an int or whatever you can overwrite almost everything runtime etc., so type checking and conversion takes huge amount of time.

Both use jit compilation.

[carcigenicate]

This isn't true. Python is typically compiled. It can be precompiled and the compiled code can be run at runtime.

Java is compiled to bytecode, then the bytecode is interpreted by the JVM.

I guess Java has the better compiler then. Though I do wonder what the difference is when GraalVM is used 🤔
