Top 7 Free Python Compilers and Interpreters

Today, we will talk about Python Compilers and discuss different compilers and interpreters available for Python Programming: CPython, Jython, IronPython, ActivePython, Nuitka, PyJS, and Stackless Python.

So, let’s start the list of available Python Compilers and Interpreters.

Python Compilers and Interpreters

Today, we will look at a list of various compilers and interpreters available for Python. You may have heard Python referred to as an interpreted language. This means a compiler converts the .py source file into a .pyc bytecode for the Python virtual machine. An interpreter executes this bytecode on the virtual machine. Let’s look at what compilers and interpreters are available for Python.

CPython

This is the default and most widely-used implementation of Python and is written in C. This is an interpreter and has a foreign function interface with languages like C. Here are some brief details:

• Developers: Python code developers, the Python community
• Stable Release: 3.6.5; March, 2018 and 2.7.15; May, 2018
• Written in: C
• Type: Python programming language interpreter

Each CPython interpreter for Python, the process uses a GIL (Global Interpreter Lock). This serves as a limitation as it disables concurrent Python threads for a process. Another problem is that to achieve concurrency, you must manage separate CPython interpreter processes with a multitasking OS. This also makes it harder for concurrent CPython processes to communicate.

Jython is JPython’s successor. It is an implementation of Python that runs on the Java platform. Here are the details:

• First Release: January 2001
• Stable Release: July 2017, version 2.7.1
• Written in: Python programming, Java
• Type: Python programming language interpreter

Jython takes Python code and compiles it to Java bytecode. This means we can run Python on any machine that runs a JVM (Java Virtual Machine). Jython supports static and dynamic compilation and let’s extend Java classes.

IronPython

This is a Python implementation around the .NET Framework and Mono.

• Author: Jim Hugunin
• First Release: September 2006
• Stable Release: February, 2018; version 2.7.8
• Written in: C#
• Type: Python programming language implementation

IronPython supports dynamic compilation and an interactive console. Python scripts are capable of interacting with .NET objects.

ActivePython

ActivePython is a Python distribution from ActiveState. It makes installation easy and cross-platform compatibility possible. Apart from the standard libraries, it has many different modules.

Nuitka

Nuitka is a source-to-source Python compiler that takes Python code and compiles it to C/C++ executables or source code.

• Developers: Kay Hayen, others
• Stable Release: October, 2017; version 0.5.28
• Type: Source-to-source compiler

Even when you don’t run Python on your machine, you can create standalone programs with Nuitka.

PyJS

PyJS is an internet application framework that will let you use Python to develop client-side web and desktop applications. You can run such an application in a web browser and also as a standalone desktop application.

Let’s take a brief look at it's details:

• Author: James Tauber
• First Release: March 2007
• Stable Release: May, 2012; version 0.8.1
• Written in: Python, JavaScript

Previously, it was called Pyjamas. It translates your Python code into JavaScript to let it run in a browser. PyJS ships with an AJAX framework and a Widget Set API.

Stackless Python

Stackless Python is a Python interpreter. It is "stackless" because it doesn’t depend on the C call for its stack. It uses the C stack and clears it between calls.

• Author: Christian Tismer
• First Release: 1998
• Stable Release: September, 2017; 3.5.4-slp
• Written in: C, Python
• Type: Interpreter

Stackless Python also supports threads and microthreads. Other than that, it provides tasklets, round-robin scheduling, serialization, and pre-compiled binaries.

So, this was all about some of the most popular Python Compilers and Interpreter. Hope you enjoyed!
