Run Python script files from C#

Important

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

Use the PythonRunner.RunFile method to execute a Python script file from C#.

Example: ensure GameObject names in the Scene

Python script

The following Python script loops over all the GameObjects in a Scene and makes sure all their names end up with an underscore.

import UnityEngine

all_objects = UnityEngine.Object.FindObjectsOfType(UnityEngine.GameObject)
for go in all_objects:
    if go.name[-1] != '_':
        go.name = go.name + '_'

Save this code as Assets/ensure_naming.py.

C# code

The following C# code creates a new menu item that calls the Python script file you just created.

using UnityEditor.Scripting.Python;
using UnityEditor;
using UnityEngine;

public class EnsureNaming
{
    [MenuItem("MyPythonScripts/Ensure Naming")]
    static void RunEnsureNaming()
    {
        PythonRunner.RunFile($"{Application.dataPath}/ensure_naming.py");
    }
}

Test

From the main menu of the Editor, select MyPythonScripts > Ensure Naming.

All the GameObjects in the Hierarchy should now be suffixed with an underscore.
