Display Python Output

Overview

Runs an inline Python script and shows its output in a dialog. Demonstrates the Python Run node.

Display Python Output

Python is a high-level programming language known for its scripting capabilities. Robomotion enables users to run Python scripts and automate complex scenarios that require a custom approach.

What Display Python Output can do

  • Run Python script (Core.Process.StartProcess) — runs python with -c 'variableName = "Hello World!"\nprint(variableName)', captures stdout into msg.python_output.
  • Trim output (Core.Programming.Function) — strips trailing CR/LF from msg.python_output.
  • Message Dialog (Core.Dialog.MessageBox, optType: info) titled Output from Python script: shows msg.python_output, then Core.Flow.Stop.

Behind the scenes

  • The inline script uses the Python 3 print(variableName) call syntax, matching the python interpreter most systems ship today. If you need Python 2 fidelity, point inFilePath at a Python 2 binary and change the call back to the print statement form.
  • Trimming trailing newlines before the dialog keeps the message box compact — print always appends a \n on stdout.
