You can use Embedded Python to write server-side code on the InterSystems IRIS for Health™. Your Python code runs side-by-side with ObjectScript code within the InterSystems IRIS kernel for tight integration with your data. You can write methods in InterSystems IRIS classes using Embedded Python or use any existing Python library from ObjectScript.
If you would rather use Python on an external server or in an external process, you can also use it as an external language.
