  Parsing Images and Charting Data with Embedded Python

  Content Type
  Exercise

  Duration
  45m

  Level
  Introductory

  Explore ways of using Embedded Python in InterSystems IRIS® data platform. Python is a popular and server-side programming languages that is beginner-friendly but also home to an advanced ecosystem of open-source libraries. With Embedded Python, you can:

  • Run Python commands from the native context of InterSystems IRIS.
  • Run a Python shell within the InterSystems Terminal.
  • Save Python scripts as packages on the InterSystems server.
  • Access all of your objects and data using InterSystems ObjectScript or Python.
  • Write an InterSystems class method in Python.

  
  

  In this exercise, you will explore an expense-tracking application that uses open-source Python libraries to parse images of receipts, calculate currency conversions, store receipt data in an InterSystems® database, and expose an API to plot total weekly expenses.

  Learning Objectives

  • Compare the use cases for the three different modes of Embedded Python.
    
  • Compare the usage of Python and ObjectScript packages.
    
  • Create a receipt-processing application utilizing ObjectScript and Embedded Python.

  What's Next?

  In this exercise, you experimented with InterSystems ObjectScript and Embedded Python, then built a simple expense-tracking application that calls Python libraries in the context of an InterSystems IRIS application. As you can see, the broad functionality of the Python open-source ecosystem is now available to ObjectScript, and the power, speed, and multi-model functionality of InterSystems IRIS is now available to Python developers.

  Here are some more ways you can use Embedded Python:

  • Import Python libraries into InterSystems IRIS using %SYS.Python.Import.
  • Run a Python shell within the InterSystems Terminal using %SYS.Python.Shell.
  • Write the body of a class method in Python using the compile flag [Language = python].
  • Save Python scripts as packages on the InterSystems server.

  
  

  Continue learning with the following content:

  • Find details on the iris Python package and the %SYS.Python package—as well as details on setting up Embedded Python (documentation, 10m).
  • Search the Developer Community for examples of how InterSystems developers have used Embedded Python.
