Run Python instructions from C#

Important

Support for the Python Scripting package is scheduled to end as of Unity 6.1.

Use the PythonRunner.RunString method to execute a single Python instruction from C#.

Example: create a menu item that executes a simple Python instruction

C# code

The following C# code creates a menu item that logs "Hello World!" in the Unity Console:

using UnityEditor.Scripting.Python;
using UnityEditor;

public class HelloWorld
{
    [MenuItem("MyPythonScripts/Log Hello World")]
    static void PrintHelloWorldFromPython()
    {
        PythonRunner.RunString(@"
                import UnityEngine;
                UnityEngine.Debug.Log('Hello World!')
                ");
    }
}

Test

From the main menu of the Editor, select MyPythonScripts > Log Hello World.

The text Hello World! should appear in the Unity Console.
