What Is JES and How Does It Work?
JES is a programming environment that allows you to create programs used for photo, video, and sound manipulation. You can also use it to create other types of graphics.
JES uses the Jython programming language. Jython is very similar to Python, and therefore follows a lot of the Python syntax. It runs on the JVM (Java Virtual Machine), meaning you also have access to Java libraries and classes.
The JES interface includes its own text editor and command prompt, so you’re able to write code and run it all in one place. This makes it a good platform for programming beginners.
How to Download and Install JES
To use JES, you will need to download and install it first.
The JES Interface
The JES interface consists of two main areas: the programming window, and the command window. The programming window acts as the text editor, and this is where you can write your Jython code.
The command window acts as a built-in command prompt. Here, you will be able to run your program, call individual functions, and execute other simple commands.
How to Run a Simple Program
Like Python, Jython uses indentation to determine the structure of your code. If you are unfamiliar with it, you can brush up onwhat Python is and what you can use it for, as well as otheruseful Python commands for beginners.
you’re able to create a program by writing some code in the programming window, and saving the file. Run your program by using the command prompt window.
Learning to Program With JES
Now that you understand the basics of JES, you can experiment more with some of the other features it has to offer. You can also start using other standard Python functions in your Jython program.
The Python Standard Library contains many functions to help with your programming tasks. Learn about the most useful and create more robust code.
