   2 days ago · Python 3.13 is the latest stable release of the Python programming language, with a mix of changes to the language, the implementation and the standard library. The biggest changes include a new interactive interpreter, experimental support for running in a free-threaded mode (PEP 703), and a Just-In-Time compiler (PEP 744).

   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 · 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.

   Sep 30, 2024 · But, the code itself may run slower than equivalent compiled code. A just-in-time, or JIT, compiler provides a kind of middle ground, where the interpreter may choose to compile some code while a program is running in order to speed it up. In Python 3.13, there’s a new, experimental JIT compiler.

   Does Python 313 have a JIT compiler?

   • Python 3.13 brings two experimental features that open the gateway to much better performance in future releases. These groundbreaking changes will require thorough testing, which is why they’re not currently enabled by default. However, you can try out free threading and the JIT compiler today by building Python from source code.

   Are CPython & PyPy JIT compilers?

   • CPython and PyPy indeed compile Python code to their own internal bytecode prior to running it. But that does not make them JIT compilers in the usual sense (which includes compilation to native code output, and tight integration with other parts of the runtime if there are any). @delnan Thanks for the clarification!

   How to enable free threading & JIT compiler in Python?

   • Navigate into the parent folder containing the Python source code, which you extracted from the downloaded archive in the previous step: Make sure to adjust the path as necessary if you opted for a more recent Python 3.13 release. Now, you can run the configure script with custom build flags to enable free threading and the JIT compiler:

   How to build Python 313 without free threading & JIT support?

   • So, you’re going to build the vanilla flavor of Python 3.13 without free threading or JIT support. Ensure that your current working directory is where you compiled Python 3.13 before, and remove any generated build files with make clean. Then, configure the build without the experimental features and compile Python again.

   What are the different types of JIT compilers?

   • There are many types of JIT compiler. Numba is a JIT. PyPy has a JIT. Java has lots of JITs. Pyston and Pyjion are JITs. The JIT that is proposed for Python 3.13 is a copy-and-patch JIT. Never heard of a copy-and-patch JIT? Don’t worry, nor had I and nor have most people.
