Running simple Python scripts inside Unity

Unity Python is a package that allows Python code to be executed as part of a Unity project. In this recipe, we'll install the package, test the Python Script Editor window with a traditional Hello World Python print statement, and create C# scripts to run Python based on the examples provided by Unity at https://docs.unity3d.com/Packages/com.unity.scripting.python@4.0/manual/inProcessAPI.html.
