   Oct 23, 2012 · To answer the question you meant to ask: CPython, 3.x or otherwise, does not, never did, and likely never will, contain a JIT compiler. Some other Python implementations (PyPy natively, Jython and IronPython by re-using JIT compilers for the virtual machines they build on) do have a JIT compiler.

   Jan 9, 2024 · To illustrate this, data from recent research “Python meets JIT compilers: A simple implementation and a comparative evaluation” showed that Java-based JITs for Python like GraalPy, and Jython can take up to 100 times longer to start than normal CPython and consume up to an additional Gigabyte of RAM to compile. There are already full JIT implementations for Python.

   You never invoke a compiler, you simply run a .py file. The Python implementation compiles the files as needed. This is different than Java, for example, where you have to run the Java compiler to turn Java source code into compiled class files. For this reason, Java is often called a compiled language, while Python is called an interpreted ...

   May 23, 2023 · Conversely, a statically compiled binary is stand-alone and can be delivered on its own to any user, whereas for interpreted or JIT compiled language, the user typically must have both the "program" (in some form) and an interpreter or JIT compiler of the right version. Bundlers do exist, but the resulting applications are even bigger than statically compiled applications.

   Jul 3, 2020 · As a JIT, it is the least interesting type and not canonically JIT compiled in the compilers sense! It compiles code right before the code needs to be used -- "just in time". Most JITs however (Pypy, Java, JS Engines), are not at all about compiling code just-in-time, but compiling optimal code at an optimal time.

   Jun 21, 2023 · Basics of Just-in-Time Compilation: Just-in-Time (JIT) compilation is a dynamic compilation technique that bridges the gap between interpreted languages and compiled languages. Unlike traditional ahead-of-time (AOT) compilation, which converts the entire codebase into machine code before execution, JIT compilation takes a different approach.

   Does Python have a JIT compiler?

   • Some other Python implementations (PyPy natively, Jython and IronPython by re-using JIT compilers for the virtual machines they build on) do have a JIT compiler. And there is no reason their JIT compilers would stop working when they add Python 3 support. But while I'm here, also let me address a misconception:

   What is a JIT compiler?

   • What people tend to mean when they say a JIT compiler, is a compiler that emits machine code. This is in contrast to an AOT (Ahead of Time) compiler, like the GNU C compiler, GCC or the Rust compiler rustc which generates the machine code once and distributes as a binary executable. When you run Python code, it is first compiled into bytecodes.

   Is JIT-compiling Python faster than interpreting Python?

   • JIT-compiling Python would be fast, as compilation + executing machine code can often be faster than interpreting. JITs improve implementations in speed by being able to optimise (compile) on information that is only available at runtime. A common theme between compiled languages is that they're statically typed.

   Which Python implementation has a JIT?

   • The only Python implementation that has a JIT is PyPy. Byt - PyPy is both a Python 2 implementation and a Python 3 implementation. There is now an experimental jit on the rust python interpreter github.com/RustPython/RustPython. The Numba project should work on Python 3.

   Does a JIT compiler compile code ahead-of-time?

   • A JIT compiler doesn't compile code Ahead-Of-Time (AOT), but still compiles source code to machine code and therefore is not quite an interpreter. JITs compile code at runtime, while your program is executing. Again, a loose model; for function := range functions { compiled_fn := get_machine_code(function); compiled_fn.execute();

   Is JIT compiled faster than native code?

   • But even if runtime state is not taken into account, JITted code can be compiled for the exact platform (processor, etc.) and so can still be faster than a compiled program which has to run on a wide variety of platforms. There is really only one advantage: Speed. Once compiled, JIT-ed code should run just as fast as native code.

   Nov 1, 2024 · Welcome to the PyPy 1.2 release. The highlight of this release is to be the first that ships with a Just-in-Time compiler that is known to be faster than CPython (and unladen swallow) on some real-world applications (or the best benchmarks we could get for them). The main theme for the 1.2 release is speed. Main site: The JIT is stable and we ...
