Python made a rather large splash at NIWeek 2018. It got a number of mentions in various settings, the most notable of which was Collin Draughon's talk "Automating Measurements with Python." LabVIEW 2018's Python Node makes it very straight-forward to call a simple Python script from within LabVIEW. You set up the Python environment, invoke the Python Node, and then tear down the environment when you're done.
Summary: Test engineers typically add manual-control screens to LabVIEW applications. While it would be helpful to repetitively execute varying parts of those manual-control screens, LabVIEW is not optimal for dynamic scripting, or on-the-fly sequencing with flow control. (Imagine editing the source code of Excel each time you wanted to create a macro.) And while Python is built for scripting, it requires advanced custom coding to interface with LabVIEW.
