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.
Sep 18, 2024 · Although the final release of Python 3.13 is scheduled for October 2024, you can download and install a preview version today to explore the new features.Notably, the introduction of free threading and a just-in-time (JIT) compiler are among the most exciting enhancements, both designed to give your code a significant performance boost.
Jan 9, 2024 · JIT, or “Just in Time” is a compilation design that implies that compilation happens on demand when the code is run the first time. It’s a very broad term that could mean many things. I guess, technically the Python compiler is already a JIT because it compiles from Python code into Bytecode.
Sep 28, 2024 · This means that JIT doesn’t waste time optimising some code which is only running once but the really hot sections of code can have heavy run-time informed optimisations done on them. Now, the JIT compiler in Python 3.13 is relatively simple and won’t be doing any crazy at this stage, but it’s a really exciting development for the future of Python performance.

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. It compiles the code on-the-fly, convertin...
To grasp the importance of JIT compilers in Python, it’s crucial to understand Python’s execution model. Python is an interpreted language, which means it translates the source code into bytecode, which is then executed by the Python interpreter. This interpretation process introduces overhead and can limit performance, especially for computational...
Python JIT compilers offer a solution to the performance limitations of interpreted execution. These compilers dynamically analyze and optimize the code at runtime, resulting in significant speedups. Let’s take a closer look at some popular Python JIT compilers:
When working with Python JIT compilers, keep the following best practices in mind: 1. Identify performance bottlenecks: Profile your code to identify sections that consume the most execution time and would benefit from JIT compilation. 2. Leverage compiler-specific features: Each JIT compiler offers unique features and optimizations. Explore the do...
Let’s provide a more detailed comparison between Cython, PyPy, and Numba, highlighting their unique features, strengths, limitations, and areas where they outperform each other:
Apr 11, 2024 · It’s clear that successfully compiling Python code at runtime requires not only high-quality Python-specific optimizations for the code being run, but also quick generation of efficient machine code for the optimized program. The Python core development team has the necessary skills and experience for the former (a middle-end tightly coupled to the interpreter), and copy-and-patch ...

Jul 3, 2020 · This gives the JITs flexibility for dynamic language features, while maintaining speed from optimized machine code output. JIT-compiling C would make it slower as we'd just be adding the compilation time to the execution time. JIT-compiling Python would be fast, as compilation + executing machine code can often be faster than interpreting.
