   Beginners assume Python is compiled because of .pyc files. The .pyc file is the compiled bytecode, which is then interpreted. So if you've run your Python code before and have the .pyc file handy, it will run faster the second time, as it doesn't have to re-compile the bytecode.

   Sep 18, 2024 · Get a sneak peek at the upcoming features in Python 3.13 aimed at enhancing performance. In this tutorial, you'll make a custom Python build with Docker to enable free threading and an experimental JIT compiler. Along the way, you'll learn how these features affect the language's ecosystem.

   Sep 30, 2024 · In Python 3.13, there’s a new, experimental JIT compiler. The fact that it’s experimental means that it’s present in Python’s source code, but it’s not enabled by default. If you want to try out the JIT compiler, you need to set up a special version of Python 3.13 with the JIT enabled.

   Jan 9, 2024 · There are two key factors that allow the Baseline JIT a speed up over the LLInt3: > Removal of interpreter dispatch. Interpreter dispatch is the costliest part of interpretation, since the indirect branches used for selecting the implementation of an opcode are hard for the CPU to predict.

   Mar 11, 2010 · The Python interpreter is easily extended with new functions and data types implemented in C or C++ (or other languages callable from C). Python is also suitable as an extension language for customizable applications. This tutorial introduces the reader informally to the basic concepts and features of the Python language and system.

   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.

   Do I need Python to compile Python?

   • Oddly enough, it may sound like you must already have Python to compile Python itself. Indeed, you need an earlier version of the Python interpreter, but only if you want to build Python 3.13 with the JIT support. That’s because the JIT build tool, which generates binary stencils for the copy-and-patch compiler, is a pure-Python script.

   How does a Python interpreter work?

   • The Python interpreter first reads the human code and optimizes it to some intermediate code before interpreting it into machine code. That's why you always need another program to run a Python script, unlike in C++ where you can run the compiled executable of your code directly. For example, c:\Python27\python.exe or /usr/bin/python.

   Does Python create a bytecode if a library is imported?

   • Python does create .pyc files (so-called byecode) whenever a library is imported. AFAIK the bytecode can only speed up load times, not execution times. @aitchnyu: Caching the bytecode in .pyc files only speeds up loading indeed, but only becase the Python code is compiled to bytecode before execution anyway.

   What is a Tier 2 interpreter in Python?

   • When you build Python 3.13 with the experimental JIT support, you’ll enable a lower-level execution layer called the Tier 2 interpreter, which breaks down Python bytecode into even more granular instructions. These micro-ops can be mapped to native machine instructions very quickly using the copy-and-patch algorithm.

   Are Python implementations interpreted or compiled to bytecode?

   • Most implementations of Python aren't interpreted but rather compiled to bytecode. @rubik, great suggestion. I would add to your list: "use existing extensions (like NumPy)". First off, Python 3 (.x) is a language, for which there can be any number of implementations.
