You could use **launch()**:

> **[launch() / Reference](https://processing.org/reference/launch_.html)**
>
> Attempts to open an application or file using your platform's launcher. The filename parameter is a String specifying the file name and location. The location parameter must be a full path name…

Or directly manipulate Java’s [Process](https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/Process.html) class as on this [example sketch link](https://forum.processing.org/two/discussion/23471/combining-two-pieces-of-code/):

This won’t work if you use the Processing PDE, but you can use py5 to make arbitrary calls from Processing to Python.

[https://py5coding.org/content/processing\_mode.html](https://py5coding.org/content/processing_mode.html)

py5’s Processing mode adds a `callPython()` method to Processing. You can pass Java objects to Python and the Python code can return Python objects back to Java.

The example code in this folder will help you:
