can stop where you feel comfortable and begin contributing immediately without
reading and understanding everything. If you do choose to skip
around within the guide, be aware that sections build on each other,
so you may find it necessary to backtrack to fill in
missing concepts and terminology.

Other interpreter implementations
---------------------------------

This guide is specifically for contributing to the Python reference interpreter,
also known as CPython (while most of the standard library is written in Python,
the interpreter core is written in C and integrates most easily with the C and
C++ ecosystems).

There are other Python implementations, each with a different focus. Like
CPython, they always have more things they would like to do than they have
developers to work on them. Some major examples that may be of interest are:

* PyPy_: A Python interpreter focused on high speed (JIT-compiled) operation
on major platforms.
* GraalPy_: A Python interpreter which has first-class support for
embedding in Java, built on GraalVM.
* Jython_: A Python interpreter focused on good integration with the Java
Virtual Machine (JVM) environment.
* IronPython_: A Python interpreter focused on good integration with the
Common Language Runtime (CLR) provided by .NET and Mono.
* Stackless_: A Python interpreter focused on providing lightweight
microthreads while remaining largely compatible with CPython specific
extension modules.
* MicroPython_: A tiny Python interpreter with small subset of the Python
standard library that is optimised to run on microcontrollers and in
constrained environments.
* CircuitPython_: A fork of MicroPython designed to simplify experimenting
and learning to code on low-cost microcontroller boards.
