- Also, it does not compile to the native machine's code. Instead, it compiles to a byte code that is used by a virtual machine. The virtual machine is itself a compiled program. This is very similar to how Java works; so similar, in fact, that there is a Python variant (Jython) that compiles to the Java Virtual Machine's byte code instead!

Two concepts might help us understand better why Python compiled to native machine code "may" not run as fast as compiled C or other commonly compiled languages. They are called early binding and late binding.

In JVM the Java Interpreter exists which interprets the bytecode line by line to get the native machine code for execution purpose but when Java bytecode is executed by an interpreter, the execution will always be slower.
Feb 26, 2012 · Python does not need a compiler because it relies on an application (called an interpreter) that compiles and runs the code without storing the machine code being created in a form that you can easily access or distribute.
Jul 11, 2015 · I can understand the fact that Java needs both a compiler and an interpreter. It compiles source code to bytecode and then a virtual machine (on Windows, on Linux, on Android, etc.) translates that bytecode to machine code for the current architecture.
Jan 13, 2022 · For native machine code, the CPU is the interpreter. You cannot execute code without interpreting it. If you have a program written in some language X, and you want to know what the result of that program is, there are only two things you can do: Interpret the program with an interpreter for language X, or.
Unlike the mainstream Java VM implementations, CPython does not subsequently compile the bytecode into native object code. There are, however, other Python implementations that work differently: There’s a Python implementation for the Java platform called Jython. It runs in the JVM, and there’s a direct interoperability between Java and Python.
Sep 6, 2021 · For example, there are compilers that can compile JVM bytecode to CIL bytecode, or to x86 native machine code (Excelsior JET, GCJ). Furthermore, many modern JVMs (including Oracle's HotSpot and Eclipse/IBM's J9) include a native code JIT compiler, so the JVM bytecode is not necessarily interpreted.
