Run Python script Action(Power Automate Desktop)

Japanese version.

This Action that executes arbitrary Python.

This is effective for processing that would be difficult to handle with actions alone, but because it involves entering the program code itself, it is recommended that it be used only minimally in environments used by non-systems engineers.

However, complex conditional expressions are too large to be built with actions, so there are cases where code is more appropriate.

How to use

Drag "Run Python script" from "Scripting" under "Actions".

Set parameters.
