Jython is the Python programming language implemented over the Java Virtual Machine.
Inductive automation ignition 7.8 and python code#
We can't take credit for this - the Jython engine hot-compiles (compiles the code when it is run) your Jython code to Java bytecode, which means it runs natively in the JVM, which in turn can hot-compile it to machine code. Many scripting users are blown away by their script's speed. For more information, see Accessing Java.

When running under the Gateway, this will be Java 8 and above. In the Client, this will be Java 6 or above. One of the powerful things about using Jython is that your script has access to the entire Java standard library. Most users of Python use the implementation called "CPython" - they just don't realize it. See (programming_language)#Implementations. Python is the language, Jython is the implementation of the language that we use. You'll often hear Python referred to as "Jython" by advanced users of Ignition.

Python Variables, Datatypes, and Operators: Learn what a variable is and how to create it, what the various datatypes are, and what operators you can use on them.It goes over all of the core concepts you will need for scripting in Ignition but then next section ( Scripting in Ignition) goes over using Python directly inside Ignition. This section is a short tutorial specifically for python, which should help get you started. If you find yourself doing a lot of scripting, you may want to pick up a basic reference book about Python, or go through a simple online tutorial course. It is frequently called "executable pseudocode". It is very easy to read - even if you don't know it at all, you will probably be able to understand a basic Python script. Python is one of the most beautiful programming languages we've ever encountered. The good news is that learning Python is easy and enjoyable. In our experience, most industrial projects involve lots of very complex and specific requirements. Jython 2.7 allows us to use the standard functions and tools in Python 2.7, so if you want to look up something in the Python docs, make sure to use version 2.7 ( ).While it is entirely possible to create a complete and powerful project in Ignition without writing a line of script, many designers will find that in order to complete projects with specific requirements, they need to learn at least a little Python. When looking at outside documentation, such as on verify that you are looking at the correct version. your Jython code is converted to Java bytecode, which means it runs natively in the JVM, which in turn can compile it to machine code. We can't take credit for this - the Jython engine compiles the code when it is run.
