7 Major Python Compilers and Interpreters – Free Online Available

1. Online Python Compilers

In our last tutorial, we studied Python Interpreters. Today, we will talk about Python Compilers, we 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 Python Interpreters.

2. Python Compilers and Interpreters

Today, we will share with you a list of various Python interpreters and compilers available for Python. You may have heard that Python is an interpreted language. Well, this is the way it goes.

  • A compiler converts the .py source file into a .pyc bytecode for the Python virtual machine.
  • A Python interpreter executes this bytecode on the virtual machine.

Let’s look at what compilers and interpreters are available for Python.

3. 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’s a brief on it-

  • 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

a. Design of CPython

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.
For more on this, you can refer to www.cython.org.

4. Jython

Jython is JPython’s successor. It is an implementation of Python that runs on the Java platform. Here’s a brief-

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

Python Compilers and Interpreters – Jython

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.

5. IronPython

This is a Python implementation around the .NET Framework and Mono. Here’s a brief:

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

6. 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.

7. Nuitka

Nuitka, source-to-source Python compilers that take Python code and compiles it to C/C++ executables or source code. Let’s take a brief:

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

8. 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:

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

Earlier, 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.

9. 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.

Here’s a brief:

  • 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 Python Interpreter and Compilers. Hope you like our explanation.

10. Conclusion

Hence, we studied a list of Python Compiler and Interpreter are available for Python Programming. With that, we have covered every popular Python compilers/interpreter. Do you want to add more to the list? Drop it in the comments.

    I appreciat all your tutorials and info, your team doing a great job
    pypy is not on The list, its the recommended compiler byGuido van Rossum and its faster than the traditional Cpython or Jython
