Jython is the JVM implementation of the Python programming language. It is designed to run on the Java platform. Jython was created in 1997 by Jim Hugunin. It closely follows the standard Python implementation called CPython. Jython 2.7.0 was released in May 2015, which corresponds to CPython 2.7. This is an introductory tutorial, which covers the basics of Jython and explains how to handle its various modules and sub-modules.

Jython programs can import and use any Java class. Except for some standard modules, Jython programs use Java classes instead of Python modules. Jython includes almost all of the modules in the standard Python programming language distribution, lacking only some of the modules implemented originally in C. For example, a user interface in Jython could be written with Swing, AWT, or SWT. Jython compiles Python source code to Java bytecode (an intermediate language) either on-demand or statically.

Jython was initially created in late 1997 to replace C with Java for performance-intensive code accessed by Python programs, moving to SourceForge in October 2000. The Python Software Foundation awarded a grant in January 2005. Jython 2.5 was released in June 2009.

Difference between Python and Jython

Following are the differences between Python and Jython −

• The reference implementation of Python, called CPython, is written in C language. Jython on the other hand is completely written in Java and is a JVM implementation.
• Standard Python is available on multiple platforms. Jython is available for any platform with a JVM installed on it.
• Standard Python code compiles to a .pyc file, while the Jython program compiles to a .class file.
• Python extensions can be written in the C language. Extensions for Jython are written in Java.
• Jython is truly multi-threaded in nature. Python however uses the Global Interpreter Lock (GIL) mechanism for this purpose.
• Both implementations have different garbage collection mechanisms.

PROS OF JYTHON:

• Very Friendly and Easy-to-Learn:

With Jython you a programmer is able to learn the basics of code writing in a week’s time. This is because Jython offers several in-depth courses on the basics of writing code. Due to its automated correcting ability, Jython also guides the new programmer step by step.

• Very Clean and Concise:

Another advantage of using Jython is that unlike Java it does not confuse the programmer through its various manual features. Jython is programming software that focuses on the idea of developing a clean and concise interface for the new programmer making it a comforting experience.

• Easy to Read:

It requires less effort to write a Python program than to write one in another language like C++ or Java. Python is easy to use and is at the same time extremely popular among many companies. There are specific companies that even prefer the use of Jython.

• Dynamically Typed:

As mentioned before Jython is a program that is dynamically typed, hence making it easier for the user to use the program and write code. The advantage of Jython lies in its very sophisticated functioning in terms of code writing and speed when saving and loading code.

• Fluid Programming:

Jython is a program that keeps the fluidity of programming intact. The programmers of various experience levels know that the writing of code is not possible without a clear head to do it. Hence Jython tries to minimize the experience of lag and effort when a writer writes code on it.

• Quite Versatile:

Since Jython is programming software that is meant to be used and be able to read the script of the Java programming software and the Python programming software, it naturally has to be a program that is versatile in its functioning when it comes to writing code.

• Large User Community:

Jython is programming software that keeps the users and the code writers connected through various online initiatives that are helpful to both parties. Here there are several forum discussions amongst the code writers on the uses and possible limitations of Jython as programming software.

• Popular Among Companies:

Jython is a software development and code writing program that is very popular with American and South Asian Information and Technology companies. It does not require the introduction of a degree in coding like the use of Java does. For this reason, it is more accessible.

• Lacks GIL:

An additional benefit for Jython, at least for some, is it lacks the GIL (the Global Interpreter Lock) and uses Java’s native threads. This means that you can run pure Python code in parallel, something not possible with the GIL. This is a great benefit for code writers.

CONS OF JYTHON:

• Slower than Other Languages:

The Jython application for developing software and the writing of code is not possible slower than other languages as it is less funded than other software. The Jython language is a good way to learn basic code writing but not a very viable option for later developments.

• Gaming:

The Jython platform for code writing and software development is most certainly not made for the development of games and code writing that involves gaming. The Jython software, because it is slow and lags from time to time, makes it impossible for gamers to write code.

• Features Provided by Other Services:

The features of Jython as a code writing software are also provided by other languages. The exact compatibility with Java is not an option that is provided by others, but several other features are provided by software development programs like Pearl C2 as well.

• Weak in Mobile Computing:

Jython is a development software that works well on computers of all forms, but it is not a good option for compatibility with mobile. Unlike other programs like Java, Jython is not compatible with mobile phones. It is well-advised to not use Jython on the mobile.

• Smartphone:

Another disadvantage of Jython is its lack of smartphone support. Not only is it not compatible with the phone, but it is also not supported by most smartphone applications, unlike development programs like Java and Python itself. This is a big drawback for developers.

• Manual Functioning:

The development software that offers the most manual functioning is naturally the one most developers will go for, and Jython is precisely one type of developing software that does not enhance manual functioning, hence reducing the capability of the developer and limiting the possibilities of code writing.

• Competition:

There is a lot of competition in the world of software development and code writing applications, and for this reason, Jython, although a very popular name in the code writing world is one that is often left behind due to more professional options like Java. Due to this competition, Jython is often not recommended by several code developers.

To sum up, one could say that Jython is definitely a programming software that could enhance the performances of the code developers who are just beginning and are trying their hand at something new.

This is the reason Jython is recommended by websites on code writing, although it receives mixed reviews from the developers themselves, who think that a little more functioning of the manual settings of the program could do well when it comes to code writing.
